Abstract
A compositon useful as an intermediate for a skin laminate and a fiber-reinforced composite comprises:(A) At least 5 wt. % of an at least partially end-capped unsaturated polyetherester wherein the end-capping compound includes a compound having at least one epoxy group;(B) an unsaturated polyester resin such that the weight ratio unsaturated polyester resin (B):polyetherester resin (A) is from about 10:90 to about 90:10;(C) from about 10 to about 70 wt. % of at least one vinyl monomer such as styrene; and(D) a curing agent such as a free radical initiator and an accelerator.
