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.
Keywords Poly ester-ether-amide poly ester-aliphatic-amide multiblock terpolymers elastomers phase structure. Melted vulcanized rubber and thermoplastic elastomers. Synthesis of block terpolymers proceeded in the two stages. The hard phase must possess a relatively large elasticity modulus, high glass transition temperature or melting point, and high density. This shows that the purity of the PTMO soft phase increases. The series differ in a chemical structure of the ester block. The poor-shaped melting endotherm is observed in the low-temperature region in terpolymers of series I.
C elaztomery of the carbonyl group.
Synthesis was carried out in a cylindrical shape with conical bottom 6-dm 3 autoclave made of stainless steel.
The second stage of the process comprises the specific condensation polymerization of mixed intermediates obtained in the first stage of synthesis. Results and discussion 3.

Properties of TPE The number of carbons x separating the terephthalate groups in the ester block of TPEs influences all their properties, which were presented in Table 3. More statistics for editors and authors Login to your personal dashboard for more detailed statistics on your publications.
Before the synthesis, the autoclave was purged three times with nitrogen at the pressure of 0. This determines a relatively small fraction of the xGT sequence in the soft phase, large degrees of separation of both soft and hard phase and comparable fraction of the respective blocks in the interphase.
It is therefore a measure of the quality and content of the continuous phase. The DSC study results for terpolymers. Therefore, they are elastomers with a better mechanical shape memory than terpoly ester-aliphatic-amide. Materials The following substrates were used: This conclusion is confirmed by the peak presence at There are three distinct regions:. Obtained oligoamids had coherent with assumed molecular weight values, didn’t contain amid groups, and may be used as hard block in various types of thermoplastic multiblock elastomers.
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.
These examples may contain colloquial words based on your search.
An increase in the number of carbons separating the terephthalate groups in the ester block of TPEEAs termopoastyczne an increase of absorbability of benzene and decrease of hardness, due to an increase in amorphous phase content.
After the reaction was completed, the obtained oligoamide was extruded by compressed nitrogen into a tube with water that was vigorously stirring with bubbling air. Alloys, preparations containing polymers, preparations containing elastomers.
MOBI SP. Z O.O.
There is no in obtained terpolymers a strong, wide termoplasttczne for the O-H stretch in the region cm -1which is observed in FT-IR spectra of pure dicarboxylic oligoamides. The same regularity is observed during cooling of the materials.
These examples may contain rude words based on your search. July 13th Published: After that, the reaction mixture was kept in the reactor under a pressure of 0.
Received two types of mechanical hysteresis loops. The elastoomery stage polycondensation was carried out for 5 h under a flow of nitrogen. The most intense diffraction peaks appear in doublets.
Such macromolecules construction allows a close proximity of the hard blocks and intermolecular interactions. 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.
The DSC curves of multiblock elastomers can be divided into two parts. CH 2 groups bonded to the C atom of the amide group. These two temperatures determine the points at which the particular elastomer goes through transitions in its physical properties [ 6 ].
