摘要

研究了以再生聚对苯二甲酸乙二醇酯为原料制备不饱和聚酯树脂的方法。研究了不饱和聚酯树脂在苯乙烯、过氧化物(Butanox 50M)和促进剂(硬脂酸钴和二甲苯胺)作用下的固化过程。研究了该树脂制备的高分子材料的物理力学性能。已经确定它们的强度取决于合成中使用的聚醚多元醇中再生聚对苯二甲酸乙二醇酯的质量分数。

Obtaining unsaturated polyester resins using recycled polyethylene terephthalate
A method for obtaining an unsaturated polyester resin based on recycled polyethylene terephthalate has been developed. The process of curing an unsaturated polyester resin under the action of styrene, a peroxide compound (Butanox 50M) and an accelerator (cobalt stearate and dimethylaniline) has been studied. The physical and mechanical properties of polymeric materials based on the developed resin have been studied. It has been established that their strength depends on the mass fraction of recycled polyethylene terephthalate in the oligoether polyol used in the synthesis.
