PURPOSE: The titled compsn. capable of heat bonding soft polyvinyl chloride to soft polyvinyl chloride or different types of substrates strongly and consistently, prepared by adding a thermoplastic polyester to polyvinyl chloride. n CONSTITUTION: The titled compsn. is prepared by adding 0.5W200pts.wt. thermoplastic polyester[e.g. those obtained by interaction of (a) a mixt. of terephthalic acid, isophthalic acid and an aliphatic dibasic acid (e.g. adipic acid, succinic acid) and (b) glycol such as 1,4-butanediol] to 100pts.wt. polyvinyl chloride. The titled compsn. improves weldability of soft polyvinyl chloride and makes it possible to heat bond soft polyvinyl chloride to soft polyvinyl chloride or different types of substrates strongly and consistently. n COPYRIGHT: (C)1982,JPO&Japio |
