COPOLYMER POLYOLS AND A PROCESS FOR THE PRODUCTION THEREOF
摘要
<p>The present inventions disclosed copolymer polyol composition which have a polymer content of 40 to 75 weight percent, based on total weight, and product stability such that essentially 100 percent passes through a 150 mesh screen produced by a free radical polymerization of the composition comprising: (a) a feedstock polyol; (b) at least one ethylenically unsaturated monomer; (c) a free radical polymerization initiator; (d) a chain transfer agent; (e) optionally a preformed stabilizer; and (f) optionally a macromer; with the proviso that at least one of e) or f) is present; wherein the feedstock has a nominal average functionality of 1.5 to 2.7, an equivalent weight of 400 to 2000. Such copolymer polyols can be used for the production of polyurethane products.</p>
