摘要:
Imide-containing polymers of styrene-type monomers are prepared by a process comprising solution polymerizing under free radical polymerization conditions a polymerizable monomer composition comprising at least one vinylaromatic monomer and at least one maleamic monocarboxylic acid monomer.

摘要:
Vinyl polymer polyols are produced by free radical polymerisation of at least one vinyl monomer (e.g. styrene, acrylonitrile, methyl methacrylate, methyl acrylate and/or butadiene) in a partially alkoxylated polyoxyalkylene amine, e.g. one having a molecular weight of 2000 to 8000. The vinyl polymer polyols react with polyisocyanates forming faster-curing flexible foams with improved loadbearing properties.
