摘　　要：介绍了光-生物降解PP餐饮具的制备。用红外光谱和力学性能衰变的方法评价其生物降解引发过程。光-生物降解作用的研究结果表明,PDPⅢ和Ⅳ降解母料添加剂是此类餐饮具生物降解引发过程的有效引发剂,而此类餐饮具具有初始力学性能优良、环境降解作用显著(羰基指数值提高达中国国家标准)、价格低廉和符合食品卫生要求等较优的综合使用性能。This thesis, we have a study on preparation of photo-biodegradable polypropylene tableware. By the way of infrared spectrometry and mechanical property decay, we also evaluate the initiation of their biodegradation and the function of their photo-biodegradation. The result of the research showed that PDP Ⅲ or Ⅳ degradable masterbatch additive is the effective initiator of the biodegradable initiation of this kind of tableware, and this kind of tableware has better comprehensive application function in environmental degradation (carbonyl group index increase value reach GB state standard), low cost and meeting the demand of food hygiene.
