ABSTRACT:
Polycaprolactone (PCL) is melted at a temperature of 60.degree. C. or higher and subsequently cooled down to a non-crystallizing temperature and exposed to radiation so that it is crosslinked and a network structure is introduced to impart heat resistance to the PCL. Because of the high degrees of its crosslinking, heat resistance and transparency, the PCL product can be used as a heat-resistant tape or a heat-shrinkable film.
