July 13th Published: The effect of temperature on the dynamic mechanical properties of TPEEA depending on the chemical structure of ester block was presented in Figures 1 7 and Polyether CH 2 groups bonded to the other CH 2 groups.
The number of carbons separating the terephthalate groups elashomery the ester block has little effect on the physical properties of the terpolymers obtained by slightly increasing the amorphous phase. CH 2 groups linked to the carbonyl group through an oxygen atom. See examples translated by elastomers 7 examples with alignment. Login to your personal dashboard for more detailed statistics on your publications.
The block copolymer will exhibit characteristics of a good elastomer if it complies with five inseparable conditions:. More statistics for editors and authors Login to your personal dashboard for more detailed statistics on your publications. This is probably due to the lower weight content of flexible blocks in the terpolymers. It is a measure of the quality of the spatial network of the elastomer.
These two temperatures determine the points at which the particular elastomer goes through transitions in its physical properties [ 6 ]. For all the series, terpolymers where the ester block is trimethylene terephtalate trmoplastyczne poor-shaped and very wide diffraction maximum. We are IntechOpen, the world’s leading publisher of Open Access books.
The properties of TPEs are influenced by an appropriate phase structure and its thermal reproducibility in the heating-cooling cycle, functional qualities large, reversible deformations and the processing properties possibility of multiple melting and solidifications.
These examples may contain colloquial words based on your search. There are three distinct regions:. The influence of chemical compositions of ester block on the functional properties and on the values of phase transition temperatures of the products have been determined.
The intermolecular interactions of rigid blocks affect the stabilization of the phase structure of the whole polymeric system. Edited by Chapal Kumar Das. Chemical shifts ppm of terpoly ester-ether-amides and terpoly ester-aliphatic-amides. Then, the pressure was reduced during 0.
However, one should bear in mind that the terpoly ester-ether-amide s and terpoly ester-aliphatic-amide s are random block polymers.
elastomery – Translation into English – examples Polish | Reverso Context
An increase in the number of carbons separating the terephthalate groups in elasomery ester block of TPEEAs causes an increase of absorbability of benzene and decrease of hardness, due to an increase in amorphous phase content. The degree of phase separation of soft phase and the degree of crystallinity of hard phase was determined by DSC analysis.
Synthesis was carried out in a cylindrical shape with conical bottom 6-dm 3 autoclave made of stainless steel. After the reaction termoplzstyczne completed, the obtained oligoamide was extruded by compressed nitrogen into a tube with water that was vigorously stirring with bubbling air.

This conclusion is confirmed by the peak presence at Flexible blocks create more and better polymer matrix and the content of crystalline phase decreases. Synthesis of multiblock thermoplastic elastomers Synthesis of block terpolymers proceeded in the two terrmoplastyczne. A detailed description of this synthesis termoplstyczne given in previous papers [ 36hermoplastyczne ]. December 7th Reviewed: The influence of chemical compositions of ester block on the thermal properties and on the values of phase change temperatures of the products are presented in Table 6 and are shown in Figures 11 — There is no in obtained terpolymers a strong, wide band for the O-H stretch in the region cm -1which is observed in FT-IR spectra of pure dicarboxylic oligoamides.
All other CH 2 groups in the oligoamide chain.
The mechanical and elastic properties of obtained polymers were evaluated. Conclusion The synthesis, structure, and properties of poly[ multi-methylene terephthalate -block- oxytetramethylene -block- laurolactam ] and poly[ multi-methylene terephthalate -block- linoleic alcohol dimer -block- laurolactam ] terpolymers have been reviewed in this chapter. This may indicate the weakest capacity for crystallization of these polymers.
A small dose of water and phosphoric acid was added to simplify the initiation of the reaction. C atoms of the amide group. Help us write another book on this subject and reach those readers. Better mechanical properties, but worst elastic residues have terpolymers where the amorphous phase is DLAol series II.

The melting point temperature increased with the increasing amounts of the carbons separating the terephthalate groups in the ester block of terpolymers. Join Reverso Register Login Facebook connect.
It determined the heat of fusion of the soft phase. Hence, these are plastics possessing at least elaatomery two values of the physical transition temperatures, i. Obtained terpolymers exhibit unique properties, such as low glass transition temperature, a wide temperature range of application, fast cristallization, good mechanical properties, including good elasticity, thermal stability, and thermal and chemical resistance, and may find application in practice.
Analysis of the 13 C NMR spectra showed the presence of all characteristic groups present in the esters, ethers or fatty acids, and amides.
Translation of “elastomery” in English
Obtained oligoamids had coherent with assumed molecular weight values, didn’t contain amid termoplastyczhe, and may be used as hard block termoplastyxzne various types of thermoplastic multiblock elastomers. The potential difference is a force that induces and stabilizes a heterophase structure [13—17]. This shows that the purity of the PTMO soft phase increases. The block copolymer will exhibit characteristics of a good elastomer if it complies with five inseparable conditions: The same regularity is observed during cooling of the materials.
