PURPOSE:To provide the subject molding material having excellent surface activity such as adhesivity and suitable as a compounding material by compounding polyacetal with an elastomer having a specific structure in a prescribed ratio. CONSTITUTION:(A) 50-99wt.% of polyacetal is mixed with (B) 50-1wt.% of a polyamideimide elastomer to provide a polyacetal oriented molding material having a tensile modulus of >=10GPa. The component B is a copolymer of (a) caprolactam, (b) at least one polymer glycol selected from polyoxytetramethylene glycol, oxyalkylene-modified polyoxytetramethylene glycols, polyoxyethylene glycol and alpha,omega-dihydroxyhydrocarbons and (c) at least one polycarboxylic acid selected from aromatic tricarboxylic acids, tetracarboxylic acids and acid anhydrides thereof. |
