EPOXIDE COMPOSITION Russian patent published in 2000 - IPC

FIELD: polymer production. SUBSTANCE: invention relates to polymer compositions based on 4,4'-isopropylidenediphenol epoxide resins and appropriate hardeners, which can be used as binding materials in production of glass-reinforced plastics, in particular shell structures. More specifically, composition, containing, wt parts: epoxide resin 100, isomethyltetrahydrophthalic anhydride as hardener 80, plasticizer 5, accelerator 1,5, and alumina powder 1.86-9.33, is distinguished by that plasticizer is mixture of alcohols derived from 1,3- dioxan and their high-boiling ethers (esters), accelerator is 2,4,6- tris(dimethylaminomethyl)phenol, and alumina is in the form of superfine powder. EFFECT: improved thermomechanical properties. 3 dwg, 2 tbl, 5 ex
