Abstract
A polymer composition is disclosed containing at least one biodegradable polymer combined with minor amounts of a non-biodegradable polymer for providing strength and improved processing. At least one prodegradant is included in the polymer composition for accelerating the degradation rate of the non-biodegradable polymer. The polymer composition is particularly well suited to producing fibers and films.
Claims26
A polymer composition comprising:
- a biodegradable polyester polymer present in the polymer composition in an amount greater than about 40% by weight;
- a polymeric strength enhancing agent comprising a polyolefin, a polyalkylene terephthalate, or mixtures thereof;
- and
- at least one prodegradant that accelerates a degradation rate of the polymeric strength enhancing agent, wherein the at least one prodegradant comprises an unsaturated carboxylic acid having a carbon chain length of from 12 carbon atoms to 26 carbon atoms, or an ester, anhydride or amide thereof.
