Abstract
Disclosed is a process for making shape memory polyphenylene sulfide, comprising: curing polyphenylene sulfide to produce cured polyphenylene sulfide; comminuting the cured polyphenylene sulfide to form cured polyphenylene sulfide particles; disposing the cured polyphenylene sulfide particles in a mold; heating the mold for flowing the cured polyphenylene sulfide; compressing, by applying a compressive force, the cured polyphenylene sulfide; cooling the cured polyphenylene sulfide; relieving the compressive force; and de-molding the cured polyphenylene sulfide to produce the shape memory polyphenylene sulfide.
