Abstract
Polymer/polyol compositions, obtained by polymerizing an ethylenically unsaturated monomer in situ in a polyol in the presence of inner-olefin containing at least 5 carbon atoms, are of lower viscosity and can provide polyurethanes having improved properties. Polymer/polyol compositions, obtained by polymerizing an ethylenically unsaturated monomer, in situ in a polyol in the presence of an azo compound and a peroxide having a 10 hours half-life period temperature which is lower by at least 10.degree. C. than that of the azo compound, have improved stability even at higher styrene content.
