The method is characterized by adding 0.01˜1.0 wt.% of a sodium hydroxide to the molten mixture of 20˜80 wt.% of a thermoplastic synthetic resin-molten solution and 20˜80 wt.% of a waste rubber powder or particle. The synthetic resin is pref. polyethylene, polypropylene, polystyrene, vinyl chloride resin, acryl resin or vinyl acetnte resin, and the waste rubber is pref. natural, synthetic, vulcanized or nonvulcanized rubber.
