MOLDED ITEM

摘要

PROBLEM TO BE SOLVED: To produce a molded item excellent in rigidity and scratch resistance by using at least one polymer having repeating units derived from a specific monomer so that the mechanically equivalent model of the item satisfies specific conditions. SOLUTION: This molded item is produced by using at least one polymer having repreating units derived from at least one monomer selected from among 2-10C olefin monomers and 4-15C diene monomers, and the mechanically equivalent model of the molded item satisfies the relations:λs <0.8 andΦ<0.05 (whereinλs is a parameter which determines the size of an amorphous part of the surface layer; andΦis the fraction of the surface layer). Bothλs andΦare dependent on various molding conditions.
