Abstract
Highly elastic films, filaments, and shaped articles can be prepared from amylose by forming a dispersion or solution of amylose in an appropriate liquid vehicle under conditions in which the molecular conformation of amylose is substantially helical, then forming a shaped article, film, or filament from the dispersion or solution and finally crosslinking the amylose with a crosslinking agent, the crosslinking agent being present in a proportion for providing an average of about 1 crosslink per 500 amylose monomer units to about 1 crosslink per 10 amylose monomer units.
