More Information
Summary:The agent consists of a homogenous fusion, containing compound A, which is a mixture consisting 3 to 55 % by weight 4-(alpha, alpha'- dimethylbenzyl)diphenylamine and 45 to 97 % by weight of 4,4'-di-(alpha, alpha'-dimethylbenzyl)diphenylamine , and compound B, which is at least one derivative of p-phenylenediamine of general formula I, where R1 is isopropyl, 1,3-dimethylbutyl, phenyl or o-tolyl and R2 is phenyl or o-tolyl, whereas the ratio of compound A and compound B in the melt is 1:3 to 3:1. The agent is suitable for stabilisation of polyolefins, rubber vulcanisates and mineral oils.
