VINYL CHLORIDE RESIN COMPOSITION FOR INTEGRAL MOLDING OF GLASS WITH VINYL CHLORIDE RESIN, AND INTEGRALLY MOLDED GLASS-VINYL CHLORIDE RESIN ARTICLE

摘要

PURPOSE:To prepare the subject compsn. which is excellent in flowability during injection molding and gives a molded article having a nontacky surface and a high surface hardness by compounding a vinyl chloride resin with a plasticizer and a specific hydrogenated terpene resin. CONSTITUTION:100 pts.wt. vinyl chloride resin is compounded with 20-150 pts.wt. plasticizer and 1-10 pts.wt. hydrogenated terpene resin of the formula having a number-average mol.wt. of 400-1,000 to give the objective compsn., which is excellent in flowability during injection molding and gives a molded article having a nontacky surface and a high surface hardness. Replacing the terpene resin in the above compsn. with 1-20 pts.wt. glass balloons having a mean diameter of 50-200mum or with 5-40 pts.wt. ethylene-vinyl acetate copolymer having a vinyl acetate content of 50-80wt.% and a melt flow rate (JIS 6730) of 40-250g/10 min gives a compsn. having properties equivalent to those of the above compsn.
