<p>The present invention discloses one kind of rapid degradable polyester polymers and their preparation methods and applications. The polyester polymers disclosed in present invention is made by polycondensation of repeat structure units, which consists of non-degradable blocks A and degradable blocks B, with formula of
This invention provides of polyester polymers not only have good machinery processing performance, but also can be quickly degraded in appropriate of environment, effective resolved the environment pollution problems resulted in the applications of such kind of polyester polymers. It satisfied the wide application demands and especially it ensured such kind of polymers can be applied in beverage bottle, food package films, shopping bags and other food package containers. In addition, the method of preparation in present invention is simple, low cost, the raw materials are easy to be obtained at low price. It is suitable to volume production and has practical value and application potentials.</p> |
