摘要:
A mixture of low and high molecular weight polyether polyols are stabilized by including in the mixture one to 10 percent by weight of a grafted polypropylene ether polyol of 2-4 hydroxyls having a molecular weight of 1500 to 3500 where the graft monomer is acrylonitrile or acrylonitrile styrene.
