摘要:
Certain aluminum salts of organic phosphorus acids are found to have a strong effect on inhibiting the epoxy cure rate in epoxy formulations. The substances act catalytically and can be used at a low level in an epoxy formulation to adjust the reactivity of a resin formulation to give longer gel times. Compositions and methods of preparing and using the compositions are disclosed.

An arylalkenyl ether oligomer is produced by the reaction of a polyhaloalkene with a polyhydroxyaryl compound. Halogenation of the resultant oligomer produces a flame retardant having both aromatic and aliphatic bromine groups.
