摘要： A biodegradable aliphatic polyester, such as polylactic acid, is mixed with a monomer having allyl and molded into a molding having the crosslinking degree of the biodegradable aliphatic polyester increased. Thereafter, the molding is exposed to ionizing radiation to thereby obtain a molding excelling in heat resistance. Triallyl isocyanurate or triallyl cyanurate is used as the monomer having allyl.

摘要： 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.
摘要翻译： 聚己内酯（PCL）在60℃或更高的温度下熔化，随后冷却至非结晶温度并暴露于辐射，使其交联，并引入网状结构以赋予PCL耐热性。 由于其交联度高，耐热性和透明度高，所以PCL产品可用作耐热胶带或热收缩薄膜。
