ABSTRACT:
Environmentally friendly, disposable, degradable and/or recyclable plastic articles are made from water soluble, miscible, high molecular weight, thermoplastic, polymeric resin blends that are comprised by weight of about 65% to 95% high molecular weight water soluble thermoplastic resin having an inverse solubility characteristic and about 35% to 5% of at least one of certain high molecular weight thermoplastic polymers that are functionally compatible (miscible) with the inversely soluble resin. The articles are insoluble when used for their intended purposes, but become soluble when exposed to tepid or cool water and degradable when buried in a land fill or compost. The inversely soluble resin comprises high molecular weight poly(ethylene oxide). The compatible polymer is selected from the group consisting of Nylon 11, Nylon 12, polycaprolactone, polycaprolactone, polyethylene-co-acrylic acid, polyethylene-co-methacrylic acid, polyethylene-co-vinylacetate and polyethylene-co-vinylalcohol. The articles are hydrodegradable, e.g., flushable, biodegradable, e.g., compostable, and can be recycled if desired, thereby eliminating the trash and garbage problems inherent in the use of nondegradable plastics.
