摘要： Provided is a functional styrene-butadiene copolymer having superior silica affinity. The copolymer is prepared by radical polymerizing a styrene monomer, a butadiene monomer and a reactive polyol monomer in emulsion state in order to maximize the mixing effect when compounding with silica. When mixed with silica, the disclosed styrene-butadiene copolymer provides excellent wet traction and superior abrasion resistance, and is suitable to be used for an industrial material of snow tires, belts, hoses, etc.

摘要： Disclosed herein is a novel stabilizer for preparing a polymer polyol, which is used to prepare polyurethane foam having improved physical properties. The stabilizer is prepared by allowing maleic anhydride to react with a polyether polyol, having an OH functionality of 3-8 and a molecular weight of 3,000-15,000, and then adding ethylene oxide to the reaction solution. Because the molecular weight and functionality of the stabilizer are increased through aging and dimerization, the stabilizer has a high molecular weight of 5,000-30,000, a high OH functionality of 6-10 and a viscosity of 3,000-15,000 cps/25° C. A polymer polyol derived from the stabilizer has low viscosity compared to those of prior products and contributes to the improvement in the physical properties of the resulting polyurethane foam.
