    摘要: A method of treating an amorphous CBDO polymer to impart self healing and shape memory properties by heat treatment, and products resulting from such method are described. An amorphous CBDO copolymer may include a copolyester prepared by reacting an aromatic dicarboxylic acid or ester or anhydride thereof, a 2,2,4,4-tetraalkyl-1,3-cyclobutanediol and 1,3-propanediol, 1,4-butanediol, or mixture thereof. The method may include heating said copolymer to a temperature above its glass transition temperature to impart self healing and shape memory properties.
