PURPOSE:A resin molding material is coated with a specific carboxylated ethylene-vinyl acetate copolymer on its surfaces to produce a resin molding material with good flowability and sufficient antiblocking properties. CONSTITUTION:An ethylene copolymer molding material or a molding material of hot-melt composition containing an ethylene copolymer is coated on its surfaces with a carboxylated ethylene-vinyl acetate coplymer obtained by neutralizing more than 50% equivalent of the carboxyls in a copolymer obtained by copolymerization of an alpha,beta-unsaturated carboxylic acid such as maleic acid or its anhydride and a vinylidene monomer of the formula (X, Y are H, chlorine, alkyl, acetoxy, carboxylic ester) in the presence of an ethylene-vinyl acetate copolymer as well as an ethylene copolymer or wax to give the objective molding material. |
