Abstract
Copolymers are provided having varying ratios of elastin and fibroin repeating units. By varying the length of segments of the elastin and fibroin repeating units, the absorption can be greatly varied. Tensile strengths remain relatively constant regardless of the composition within the prescribed ranges. The copolymer compositions and recombinant fibroin can be used for the production of a wide variety of formed objects and amorphous masses for use as implants.
