Temperature dependence of the properties of composites based on polyethylene and pearlite

Autor: M.A. Gevorgyan, O.G. Sel'skaya, Yu.M. Sivergin, L.A. Novokshonova

Publikováno v: Polymer Science U.S.S.R.. 24:171-178

The properties of composites based on high density polyethylene (PEHD) have been investigated. It was found that under TGA conditions thermooxidative degradation rates of PEHD are higher in composites filled with expanded pearlite with a particle siz

Autor: O.G. Sel'skaya, M. G. Chauser, V.D. Yermakova, A.A. Berlin, M. I. Cherkashin

Publikováno v: Polymer Science U.S.S.R.. 16:752-761

During copolymerization of p-diethynylbenzene with phenylacetylene using an (iso-C4H9)3AlTiCl4 catalytic system, soluble products of copolymerization contain polyene fragments, as well as polyphenylene independent of the-initial molar ratio of mon

Publikováno v: Journal of Thermal Analysis. 8:431-442

Thermal transformations of oligoarylenes, relating to polymers with conjugate systems, have been investigated in air and in vacuo, depending on the molecular weight and degree of branching of the original material. The extreme character of the thermo
