| abstract |
This invention relates to shape memory block copolymers comprising: at least one switching segment having a T trans from 10 to 70° C.; and at least one soft segment, wherein at least one of the switching segments in linked to at least one of the soft segments by at least one linkage, and wherein the copolymer transforms from a first shape to a second shape by application of a first stimulus and the copolymer transforms back to the first shape from the second shape by application of a second stimulus. The shape memory block copolymers may be biocompatible and biodegradable. |
