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.
Obtained copolymers had all characteristic FT-IR bands for esters, aliphates or ether, and amides. Aromatic C-H out of plane bonds.

Elastomwry and assignments of FT-IR band exhibited by obtained terpolymers. On the 13 C NMR spectrum the peak presence at Signals are noted in the range There are three distinct regions: A small dose of water and phosphoric acid was added to simplify the initiation of the reaction.
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 — The second step was polycondensation reaction of two previously prepared intermediate compounds.
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 Results and discussion 3.
Therefore, they are elastomers with a better mechanical shape memory than terpoly ester-aliphatic-amide. They combine the end-use physical properties of vulcanized rubbers with the easy processing of thermoplastic [1—5]. A detailed description of this synthesis is given in previous papers [ 3637 ]. Preparation termoplsatyczne terpolymers relies on the replacement in the poly multi-methylene terephthalate macromolecule xGTa certain part of fragments originated from the terephthalic acid by the dicarboxylic oligoamide block, which was derived from glycol by the oligoetherdiol or alifatic block Figure 2.
Introduction A growing demand for polymeric materials in the packaging, sport, automotive, and medicine industries stimulates the search for innovative materials with thermal termopplastyczne mechanical properties individually tailored for a given field.
July 13th Published: The mechanical eelastomery loops of terpoly ester-ether-amide s series I demonstrate that there is in these ttermoplastyczne a small energy accumulation in the first cycle. Synthesis of poly ester-b-ether-b-amide terpolymers was a two-step process in the presence of a titanate catalyst.
Our readership spans scientists, professors, researchers, librarians, and students, as well as business professionals. The poor-shaped melting endotherm is observed in the low-temperature region in terpolymers of series I. Melted vulcanized rubber and thermoplastic elastomers.

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.

This shows that the purity of the PTMO soft phase increases. November 26th DOI: Moreover, these blocks should ensure weak intermolecular interactions and a large capability for motion and rotation of short sequences of chains. Usage of sebacic acid as the molecular weight stabilizer leads to dicarboxylic oligoamids.
The following substrates were used: 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.

These two temperatures determine the points at which the particular elastomer goes through transitions in its physical properties [ 6 elasotmery. Many other uses are in the fields of paints and coatings, adhesives, sealants including weather resistant sealing materialelastomersand footwear. 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.
