Elastomers crosslinked by polylactic acid |
| abstract |
A composition is provided, which comprises chains comprising a first graft copolymer of a first elastomer and a poly(L-lactic acid), and chains comprising a second graft copolymer of a second elastomer and a poly(D-lactic acid). At least some of the poly(L-lactic acid) and poly(D-lactic acid) crosslink the chains. Poly(L-lactic acid) and poly(D-lactic acid) may form stereocomplexes that crosslink the chains. The chains may be crosslinked by crystalline structures formed from at least some of the poly(L-lactic acid) and poly(D-lactic acid) in discrete regions. The crosslinked chains may form a matrix. In a method of forming the composition, the first and second graft copolymers are mixed, such as by melt blending or solution casting, to form the composition. The graft copolymers may be formed by a “grafting-though” or “grafting-from” process. The composition may be useful under a relatively wide range of temperatures. |
