Description

(54) COMPOSITION BASED ON POLYTRICHLORBUTADIENE

one

The image refers to the rubber industry, in particular to the polygrichlorbo- gadiene-based composite.

A known composition based on polyglychlorobutadiene, comprising a stabilizer-epoxy resin in an amount of 0.5-1 parts by weight. at SO weight.h. polytrichlorbutadiene (PTHB) U.

The purpose of the invention is to increase the thermal and light stability of the composition based on PTHB.

The goal is achieved by the fact that a PTHB-based composition (in the form of a latex) is designed to act as a stabilizer C of the form of 1O- (X-naphthyl ester 2,2-methnlenbis (4-meth l-6-tert-butylphenyl) phosphorous acid

or Stafor II-2,2-methylenebis (4- / 1-methyl-6-gretbutylphenyl) phosphorous acid

Characteristics of Сgafor U and Crojjopa 11 are given in table. I.

The stability of the obtained polktrichlorbutadiene is estimated by the method of Ex-IR specter-lux — by the value of the induction period of oxidation t (based on the occurrence of the 172O carbonyl band). The aging is carried out by accelerated methods: UV irradiation - by the mercury-chkvartsy pampa PRK-4, thermal aging - in a heating cabinet in an atmosphere of air at 100 C. Pr n m f (f) 1.
