高性能聚酯-醚二醇的合成及应用
Synthesis and Application of High Performance Polyester-Ether Glycol
摘要
Abstract
Polyester-ether glycol was synthesized with poly(polyol adipate)as starting agent,epoxy alkane as the polymerization monomer,and alkali metal as catalyst.The effects of catalyst dosage on the polymerization was discussed,and its structure was characterized by FTIR and GPC.The self-made polyester-ether glycol was used to prepare polyurethane high-resilience foam and polyurethane elastomer,and the effects of polyester-ether glycol on their mechanical properties were studied.The results showed that the optimum catalyst concentration was 0.6% .When polyester-ether glycol was applied to polyurethane high resilience foam with the addition amount of 15%,it had a significant effect on improving the mechanical properties of the products.Compared with traditional propylene glycol polyether,polyurethane synthesized with polyester-ether glycol had significant advantages in mechanical properties.关键词
