Abstract
An object of the present invention is to provide a practical compatibilizing agent which makes it possible to convert the resin mixture into a homogeneous resin mixture free from separation and to eliminate defects caused by separation on molding by prevention of the separation between the radical polymerizable unsaturated resin and low profile additive, which could have not been attained by the prior art. This compatibilizing agent is a compatibilizing agent for compatibilizing a radical polymerizable unsaturated resin with a polymer containing styrene as a principal component, said compatibilizing agent being a compound (D) obtained by reacting a polymeric compound (A), a polymeric compound (B), and a compound (C), characterized in that: the polymeric compound (A) is at least one polymeric compound which is a polymer containing styrene as a principal component and has within a molecule one or more functional groups capable of reacting with the compound (C); the polymeric compound (B) is at least one polymeric compound having within a molecule one or more functional groups capable of reacting with the compound (C), which is selected from polyester, polyether, and polycarbonate; and the compound (C) is a compound which, within a molecule, has one or more functional groups capable of reacting with the polymeric compound (A) and has one or more polyfunctional groups capable of reacting with the functional group of the polymeric compound (B).
