沉淀聚合 meaning in Chinese

precipitation polymerization

These copolymer were prepared by using naclo3 nahso3 as the initiator in water precipitation polymerization . their properties were studied by means of ftir , nmr - h1 , ubbelodhe viscosimeter
作为基体所采用的三种共聚物均以以水溶性的氧化还原体系为引发剂，采用水相沉淀聚合法制备。
The results indicate that the product of precipitation polymerization has a higher molecular weight and is better in the capability of inhibiting clay expansion than that of water solution polymerization
结果表明：沉淀聚合产物分子量高于溶液聚合产物的分子量，在抑制粘土颗粒膨胀性质上优于溶液聚合产物，对提高水溶性聚合物在油田化学领域及其它方面的应用，有着积极的意义。
Abstract : water solution polymerization and precipitation polymerization of ethenyl radical monomers were carried out at same conditions , and the differences between the products in molecular weight and other aspects were investigated
文摘:针对目前溶液聚合体系中、后期粘度高，热扩散不利，从而影响分子量提高的问题，进行乙烯基类单体在同等条件的水溶液聚合及沉淀聚合，比较了获得的聚合物产物在分子量及应用性质上的差异。
