ENVIRONMENT DEGRADABLE VINYL CHLORIDE-BASED RESIN MOLDING

摘要

PURPOSE:To obtain molding promoting decomposition deterioration and oxidation deterioration in a natural environment, degradable with small force, reducible in soil by blending a vinyl chloride-based resin with an uncrosslinked polyolefin-based polymer and a transition metal-containing compound and molding. CONSTITUTION:(A) 100 pts.wt. vinyl chloride-based resin is blended with (B) 3-20 pts.wt. uncrosslinked polyolefin polymer having 7.8-9.4 solubility parameter and (C) 0.02-5 pts.wt. compound containing a transition metal to give and receive only one electron and molded to give the objective molded article comprising the component A dispersed in a state of islands having 0.2-2mum average size in the component B.
