Abstract
A thermoplastic resin composition comprising a thermoplastic resin (A) and a thermoplastic polymer (B) having a glass transition temperature within the range of from -20.degree. C. to 70.degree. C. which are melt-blended in a proportion (A)/(B) of from 95/5 to 20/80 in weight ratio. The composition, upon application of an external stress in a temperature region of from a temperature about the glass transition temperature of the thermoplastic polymer (B) to the melting point thereof, is transformable to any shape that conforms to that stress, and is capable of becoming fixed to the transformed shape in a temperature region lower than the glass transition temperature. The composition can be used to provide a temperature-dependent shape-transformable/fixable product formed of the above composition.
