【Abstract】 Ring-opening polymerization of D 4 and emulsion co-polymerization of acrylate monomers take place simultaneously under the same environments (pH=4.0, in an aqueous medium). As a result, a simultaneous latex interpenetrating polymer network of polysilicone-acrylic resin was achieved. This IPN possessing good compatibility and emulsion stability exhibits both optimum film performance and film integrity, when applied for leather finishing, wax, slip and nature hand are imparted. If added to topcoats, the water and solvent-resistance of coating layer were obviously improved.更多还原
