Thermal effects are a major factor in polymer deterioration . 热效应是聚合物劣化中的一个主要因素。
The use of wax to inhibit ozone deterioration probably goes back to 1881 . 使用蜡来抑制臭氧劣化可追溯到1881年。
Cleavage of secondary bonds can also be responsible for polymer deterioration . 次价键的分裂往往也能引起聚合体劣化。
Organisms that cause polymer deterioration include bacteria, fungi, marine animals, and borers of various types . 能够造成聚合物劣化的生物体很多,如细菌、真菌、海生动物和各种蛀虫等。
Impurities that promote deterioration of polymers can be foreign materials, such as residues from polymerization catalysts . 促使聚合物劣化的杂质可能是外加的物质,如残存的聚合用催化剂。
