Abstract
An injection molding method, including injecting a resin composition for molding as a raw material, the resin composition including at least two resins having different apparent viscosities at 230° C. and at least one compatibilizer.
Claims17
An injection molding method, comprising injecting a resin composition for molding as a raw material, the resin composition comprising at least two resins having different apparent viscosities at 230° C. and at least one compatibilizer.
A resin composition for molding, comprising at least two resins and at least one compatibilizer, wherein the resins comprise a resin A and a resin B, a difference in apparent viscosity between the two resins with a smallest difference in apparent viscosity at 230° C. among the at least two resins being from 1000 Pa·s to 50000 Pa·s.
A molded body, comprising:
- a core portion that comprises a cured product of a resin A;
- a shell portion that comprises a cured product of a resin B and that covers at least a part of the core portion;
- and
- an intermediate portion that is located between the core portion and the shell portion and that comprises a cured product of at least one compatibilizer,
- wherein concentrations of the resin A and the resin B each have a distribution that continuously changes from the core portion toward the shell portion.
