Multiblock Elastomers TPEAA and TPEEA: Physical Structure and Properties.

A three series of terpolymers composed of the blocks PTMO (M = 1000 g/mol) or DLAol (M = 540 g/mol), PA12 (M = 2000 g/mol) and xGT (DP = 2) with various chemical compositions of ester block were obtained. The series differ in the chemical structure of the flexible block and weight content of the soft phase. The effect of the number of carbons dividing the terephthalate groups on the synthesis, structure and properties of these elastomers has been investigated.

Preparation and Characterization of Potato Starch Copolymers with a High Natural Polymer Content for the Removal of Cu(II) and Fe(III) from Solutions.

Cross-linked potato starch (StMBA) and starch-g-polyacrylamide materials with a high content of natural polymer from 60 to 90 wt.% (St60-St90) were synthesized by double chemical-chemical modification (grafting and cross-linking). Eco-friendly starch absorbents were tested for removal of Cu and Fe from aqueous solutions.

Hydrophilic Films Based on Carboxymethylated Derivatives of Starch and Cellulose.

The carboxymethylated derivatives of starch (CMS) and cellulose (CMC) were used for film preparation. The infrared spectroscopy revealed that crosslinking via ester bridges with citric acid occurred between the two polysaccharide derivatives. The effect of polysaccharide derivatives ratio on physicochemical properties of prepared films was evaluated.

Influence of e-Beam Irradiation on the Physicochemical Properties of Poly(polyol Succinate-co-Butylene Succinate) Ester Elastomers.

The purpose of this research was synthesis and electron beam modification of novel ester elastomers consisting of sugar alcohol-succinic acid block and butylene glycol-succinic acid block. Four different alditols were used in the synthesis-sorbitol, erythritol, xylitol, and glycerol. The materials were irradiated with doses of 50, 100, and 150 kGy in order to determine which dose is the most beneficial.
