POLYMERIC COMPOSITION Russian patent published in 1995 - IPC

FIELD: polymeric materials. SUBSTANCE: polymeric composition is prepared by mixing components in extruder, mas. p. polyalkyleneterephthalate 100; high-molecular modified epoxy resin 2-10; (di)anhydride of aromatic di-, tri- or tetracarboxylic acid 0.2-1.0; thermostabilizing agent 0.2-2.0, and filler 2-90. High-molecular epoxy resin is prepared by interaction of low-molecular epoxydiane resin with molecular mass 340-600 with technical dihydroxyphenylsulfone, phthalic anhydride and tri-(p-aminophenyl)-methane at their mass ratio (50-94):(4.8-27.5):(0.5-14.5):(0.7-8.0), respectively. Articles were made on the basis of composition proposed by casting under pressure. EFFECT: improved method of composition preparing. 4 tbl
