A new class of compounds: R--W--R' were R and R' are identical oxy radicals containing peroxide functions such as dialkyl or diaralkyl peroxide, peroxyketal, peroxyester, or monoperoxycarbonate, and W is a carbonyl group, or carbonyl containing group, or an alkylidene or aralkylidene group, or a phosphorus containing group. Examples Di[1,3-dimethyl-3-(t-butylperoxy)butyl]carbonate; Di[1,3-dimethyl-3-(n-butoxycarbonylperoxy)butyl]carbonate; 2,2-Bis[3,3-di(t-butylperoxy)butoxy]propane; Di[1,3-dimethyl-3-(t-butylperoxy)butyl]ethyl phosphate. They are free radical affording compounds useful in crosslinking of polyolefins and unsaturated polymers, and for the polymerization of vinyl monomers and diolefinic monomers.
一种新的化合物类别:R-W-R',其中R和R'是相同的含过氧化物功能的氧自由基,例如二烷基或二芳基过氧化物,过氧乙酰甲酸酯,或单过氧碳酸酯,而W是一个羰基基团,或含羰基基团的基团,或一个烷基亚甲基或芳基亚甲基基团,或一个含磷基团。例如:Di[1,3-二甲基-3-(叔丁基过氧)丁基]碳酸酯;Di[1,3-二甲基-3-(正丁氧羰基过氧)丁基]碳酸酯;2,2-双[3,3-二(叔丁基过氧)丁氧基]丙烷;Di[1,3-二甲基-3-(叔丁基过氧)丁基]乙基磷酸酯。它们是自由基供体化合物,在聚烯烃和不饱和聚合物的交联以及乙烯单体和二烯单体的聚合中有用。
