STYRENIC RUBBER-CONTAINING RESIN COMPOSITION FOR IMC, AND MOLDED PRODUCT BY IMC

摘要

PROBLEM TO BE SOLVED: To provide a styrenic rubber-containing resin composition for IMC, exhibiting excellent adhesion to a covering material and capable of being coated at a uniform thickness when being applied to the IMC; and to provide a molded product by the IMC, obtained by molding and coating by the IMC by using the styrenic rubber-containing resin composition. SOLUTION: The styrenic rubber-containing resin composition as a base material resin usable for an inmold coating molding (IMC) method using a radically curable inmold coating composition as a coating agent comprises (A) a resin and (B) a radical scavenger, and satisfies the following conditions: (a) the compounded amount of the total of the radical scavenger (B) based on 100 pts. wt. resin component (A) is 0.01-0.3 pts. wt.; and (b) the deflection temperature under load of the styrenic rubber-containing resin composition measured by ISO 75 (A-method) is not lower than the curing temperature. The molded product by the IMC is obtained by molding the styrenic rubber-containing resin composition by the inmold coating and molding method using the radically curable inmold coating composition.
