Influence Factors on Preparation of High-solid Content Low-viscosity Polymer Polyols
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%.
