Abstract: The synthesis of thioether-bearing hyperbranched polyether polyols based on an AB/AB2 type copolymerization (cyclic latent monomers) is introduced. The polymers are prepared by anionic ring-opening multibranching copolymerization of glycidol and 2-(methylthio)ethyl glycidyl ether (MTEGE), which… read more here.

Abstract: Abstract Flexible polyurethane foams (FPUs) having polystyrene (PS) stabilized by silica gel or polystyrene-acrylonitrile (SAN) particles were synthesized employing polymer polyether polyols (PPPs). The filler and its content effect on physical, mechanical and thermal properties… read more here.

Abstract: CO2 adducts from hydrophobically-modified polyethylenimines (PEIs) in powder form are newly-developed environment-friendly blowing agents for polyurethanes (PUs). However, they are difficult to disperse into foaming systems that usually contain polyether polyols as the PU soft… read more here.
