The invention relates to the assembling cymene ethylene-ethylene carbonate and the producing process, characterized in that the constitutional expressed by the formula one and two and the corresponding aether segment compose the random copolymer which the average relative molecular mass is between the 35000 and 60000; according to the 100 percentage mass fraction calculating, the constitutional unit of the formula one greater than 50%30% greater than the constitutional unit of the formula two greater than 020% greater than the aether segment greater than 0, the loading duality zinc poly-carboxylate is used for the activator and the propylene oxide, the ethylene oxide and the carbon dioxide act together to gain the production. The virtues of the invention are the easy technics and the cheap cost of material. Comparing the existing binary copolymer, the ability of the degradation is improved highly and the thermal characteristics absent of the evident variety so the mew approach of the industrialized application of the carbon dioxide plastic is exploited. |
