The study investigates the effects of various structural parameters on the biodegradability of plastics. It includes a determination of the effect of molecular weight and polymer end group composition on the biodegradability of polyethylene and polystyrene, and an evaluation of the biodegradability of various block, graft and random copolymers containing polyethylene or polystyrene chain segments. Also included is a study of the biodegradability of organic chemicals used commercially as additives to plastics. The study verifies the popular belief that the current high volume, high molecular weight packaging plastics are not biodegradable at practical rates. The report also establishes that the structural modification of polyethylene and polystyrene by random copolymerization with other monomers will not lead to biodegradability. (Author)
