POLYMERIC COMPOSITION Russian patent published in 2005 - IPC

Abstract RU 2261878 C1

FIELD: organic chemistry, polymers, chemical technology.

SUBSTANCE: invention relates to compositions of polybutylene terephthalate (PBTP) used as constructive material. Invention proposes addition to polymeric compositions polyformal oximate (PFO1) as a modifying agent based on 4,4'-diacetyldiphenyl ester diketoxime of the formula: with value of reduced viscosity in chloroform η_rv = 0.6-0.63 dl/g in the following ratio of components, wt.-%: PBTP, 99.0-99.5, and PFO1, 0.05-1. Invention provides enhancing thermostability of PBTP in its processing, improving its deformation-strength indices.

EFFECT: improved and valuable properties of composition.
