摘　　要：用含氢硅油对八甲基环四硅氧烷开环聚合有机硅乳液进行了改性。试验结果表明,含氢硅油的引入可以显著提高聚合物的交联度,增大聚合物的分子质量,单体的转化率可以提高到90%以上。含氢硅油改性的乳胶数均直径由改性前的50nm左右增大到85nm左右。The silicone leather handle agents prepared by D4 （octamethy cyclotetrasiloxane） ring open polymerization was modified by hydrogen - containing silicone. It shows that the introduction of hydrogen - containing silicone could improve the cross linking degree greatly, and the molecular weight of the polymer increases, the monomer conversion rate improves to more than 90%. The grain radius of the emulsions was increased from approximately 50 nm to 85 nm.
