Thermal Stability of Highly Filled Cellulosic Biocomposites Based on Ethylene-Vinyl Acetate Copolymer.

The effect of plant-based fillers on thermal resistance in highly filled biocomposites based on ethylene-vinyl acetate copolymer (EVA) was studied. Wood flour and microcrystalline cellulose were used as fillers. It was shown that the introduction of microcrystalline cellulose into EVA did not affect the thermal stability of the polymer matrix.

Anionic Polymerization of Para-Diethynylbenzene: Synthesis of a Strictly Linear Polymer.

Anionic homo- and copolymerization of -diethynylbenzene in the presence of n-BuLi in polar solvents was carried out. The use of hexamethylphosphortriamide (HMPA) makes it possible to synthesize a completely linear soluble polymer that does not have branching and phenylene fragments. A copolymer of -diethynylbenzene with diphenyldiacetylene was synthesized.
