TETRAKIS (3- (3,5-DI-TERT.BUTYL-4HYDROXYPHENYL) PROPIONYLOXYMETHYL METHANE OF AMORPHER STRUCTURE, METHOD FOR ITS PRODUCTION AND ITS USE AS A STABILIZER.

摘要

Tetrakis[3-(3,5-di-tert.butyl-4-hydroxyphenyl)-propionyl-oxymethyl]met hane with amorphous structure, with glass transition temperature Tg comprised within the range of from about 40 DEG C to 50 DEG C and free from endothermic melting peaks at temperatures higher than 50 DEG C and of up to 200 DEG C is obtained by means of the melting of crystalline tetrakis[3-(3,5-di-tert.butyl-4-hydroxyphenyl)-propionyl-oxymethyl]met hane and sudden cooling of the molten material.
