The following terpolymers were elsatomery for this research study:. Moreover, these blocks should ensure weak intermolecular interactions and a large capability for motion and rotation of short sequences of chains.

The second step was polycondensation reaction of two previously prepared intermediate compounds. Introduction A growing demand for polymeric materials in the packaging, sport, automotive, and medicine industries stimulates the search for innovative materials with thermal and mechanical properties individually tailored for a given field.
Terpolymers of this series, similar to PEE elastomerry PEA, exhibit a large part of energy accumulated during the first cycle of elongation.
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 termoplastycsne. An increase in the number of carbons separating the terephthalate groups in the ester block of TPEEAs causes an increase of absorbability of benzene and decrease of hardness, due to an increase in amorphous phase content.
These two temperatures determine the points at which the particular elastomer goes through transitions in its physical properties [ 6 ]. November 26th DOI: Materials The following substrates were used: Flexible blocks create more and better polymer matrix and the content of crystalline phase decreases. Synthesis of block terpolymers proceeded in the two dlastomery.
Aromatic C-H out of plane bonds. 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. The hard phase must possess a relatively large elasticity modulus, high glass transition temperature or melting point, and high density. eladtomery
Band frequency, ppm Chemical structure Signals are noted in the range The difference between the molecular weight values, calculated from the amounts of the carboxylic groups and the assumed theoretical values do not exceed 2.
The most intense diffraction peaks appear in doublets. Better elastic properties are exhibited by terpolymers of series I, where the soft phase is PTMO because these block is more flexible large capability for motion and rotation of ether bond. 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. The ratio of height to reactor diameter is h: Keywords Poly ester-ether-amide poly ester-aliphatic-amide multiblock terpolymers elastomers phase structure.
TPEs are considered as polymeric materials, in which, as a result of the phase separation, at least two phases soft and hard are distinguished, which must be thermodynamically immiscible to prevent the interpenetration.

Probably, in these terpolymers the interphase is smaller because of weak mixing of ester blocks with DLAol matrix. Then, the pressure was reduced during 0. Polyether CH 2 groups bonded to the other CH 2 elasyomery.
Synthesis of multiblock thermoplastic elastomers Synthesis of block terpolymers proceeded in the two stages. Probably, further increase in T g1 is responsible for the terpolymers dissolution of the short ester sequence in the soft phase.

The second stage of the process comprises the specific condensation polymerization of mixed intermediates obtained in the first stage of synthesis. Absorbability increases with increasing mobility of the macromolecules and decreases with an increase in cohesive energy between them. The mechanical hysteresis loops of terpoly ester-ether-amide s series I demonstrate that there is in these materials a small energy accumulation in the first cycle.
This shows that the purity of the PTMO soft phase increases. It proves that these blocks are built into the copolymer macromolecule. Join Reverso Register Login Facebook connect. The area C is proportional to the accumulated energy.
