The invention relates to a radical polymerizable unsaturated resin compound applied to a molded material which can provide a molded product with superior surface smoothness without shrinkage at the time of curing by means of a block copolymer, and a method of manufacture of a block copolymer which is used as a block copolymer curing low-profile additive for this. The radical polymerizable unsaturated resin compound of the invention can be used to advantage in SMC and BMC using unsaturated polyester resin and can provide a molded product with superior surface smoothness, paintability, physical strength, and pigmentability.
