Abstract
The presently disclosed formula utilizes a composition of a rigid, semi-crystalline polymer, such as polybutylene terephthalate, and an amorphous polymer, such as poly(vinyl acetate), to create a thermoplastic shape memory polymer that can be processed through methods such as extrusion and injection molding, which require high heat. The polybutylene terephthalate acts as a cross-linker for the poly(vinyl acetate), therefore the thermoplastic shape memory polymer that is created has a much higher melting point and greater heat stability than other shape memory polymers.
