摘　　要：介绍了制备高固含量低黏度聚合物多元醇(POP)的工艺历程,讨论了大分子单体、链引发剂、链转移剂等对制备POP指标的影响。结果表明,选定用4或6官能度大分子单体作为稳定剂且质量分数为3%、链转移剂异丙醇(IPA)质量分数为10%、新型自由基引发剂V601质量分数为0.3%时,可以制得高固含量、低黏度、高稳定性的聚合物多元醇。The preparation process of high solid content and low viscosity polymer polyols(POP)was introduced.The effects of macromolecular monomers types,dosage,chain initiators and chain transfer agents on the preparation of POP were discussed.The results showed that the polymer polyols with high solid content,low viscosity and high stability could be prepared,when the 4 or 6 functional macromolecular monomer was selected as stabilizers with a mass fraction of 3%,chain transfer agent isopropanol with a mass fraction of 10%,and the new free radical initiator V601 with a mass fraction of 0.3%.
