摘要： Methyl propyl ketone peroxide formulations are claimed that can be safely handled at ambient temperature, are storage stable, and give fast curing rates of unsaturated polyester resins particularly when accelerated with a complex of two different metals. The claimed products are particularly suited for thin articles and coating such as suited for use in gel coat systems. The pure ketone peroxides consist of more than 60% by weight of type-4 methyl propyl ketone peroxide and used as formulations containing sufficient amount of a non-aqueous phlegmatizer.

摘要： The present invention relates to a new class of peroxides and to a process for the preparation of these peroxides having the general formula (I), wherein n=1 or 2, R1, R2, R4, R5, and R6 are independently selected from the group comprising hydrogen, C1-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aryl, C7-C20 aralkyl, and C7-C20 alkaryl, or R1 and R2 form a C3-C12 cycloalkyl group, which groups may include linear or branched alkyl moieties; and each of R1, R2, R4, R5, and R6 may optionally be substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl, aryloxy, halogen, ester, carboxy, nitrile, and amido, and R1 and R2 may form a ring, and R3 is independently selected from the group comprising C1-C20, alkyl; C3-C20 cycloalkyl, C6-C20 aryl, C7-C20, aralkyl, and C7-C20 alkaryl, which groups may include linear or branched alkyl moieties; and R3 may optionally be substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl, aryloxy, halogen, ester, carboxy, nitrile, and amido, and any pair of the optionally substituted R3, R4, R5, and R6 may form a ring, comprising the reaction of the corresponding ketone.
