    • Organic peroxydicarbonates represented by the following graphic formula are described. ##STR1## In the formula, R and R' are each selected from an alkyl group containing from 1 to 4 carbon atoms, a cycloalkyl group of from 5 to 7 carbon atoms, a C.sub.1 -C.sub.4 alkyl substituted cycloalkyl group, or participate in a cycloalkyl group having from 5 to 7 carbon atoms, provided that when one of R and R' is cycloalkyl, the other is alkyl. The peroxydicarbonates are useful as initiators for the polymerization or copolymerization of ethylenically unsaturated monomers or the cross-linking of unsaturated polyester resins. The organic peroxydicarbonates can be used in combination with commercially available peroxydicarbonates, particularly those having a shorter half-life.
    • 描述由以下图形公式表示的有机过氧化二碳酸酯。 在该式中,R和R'各自选自含有1至4个碳原子的烷基,5至7个碳原子的环烷基,C 1 -C 4烷基取代的环烷基,或者参与 具有5至7个碳原子的环烷基,条件是当R和R'中的一个是环烷基时,另一个是烷基。 过氧二碳酸酯可用作烯属不饱和单体的聚合或共聚的引发剂或不饱和聚酯树脂的交联。 有机过氧碳酸氢盐可以与市售的过氧化二碳酸酯组合使用,特别是半衰期较短的那些。

      and n is 2 by reacting a t-aliphatic Alpha -chloroazo compound

      with peracids or their salts selected from

      with the corresponding acylating agent; and the use of these compounds as polymerization initiators for vinyl monomers and as curing agents for resins. For example, 2-t-butylazo-2(acetylperoxy)-4-methylpentane is prepared by reacting the sodium salt of 2-t-butylazo-2-hydroperoxy-4-methylpentane with acetyl chloride; and the product used to polymerize vinyl chloride at 30*C. and to cure unsaturated polyester-styrene resins at room temperature.
