Abstract: A dual cure system including at least two different and separate types of chemical reactions occurring as the process of the present invention proceeds including, for example, the following two reactions: (1) free radical polymerization of methacrylated or acrylated polyol; and (2) an epoxy-curing agent reaction. The dual cure system of the present invention advantageously provides a first cure reaction of methacrylated or acrylated polyol followed by a second epoxy-curing agent thermoset reaction to form a cured thermoset exhibiting an elongation property of greater than about 5%.
