    • A polyisoprene emulsion is provided, being made from 60˜100 parts by weight of isoprene monomer and 5˜50 parts by weight of one or more monomers selected from the group consisting of styrene, acrylates and organic acids, by using a free radical emulsion polymerization in the presence of an emulsifier and an initiator, said polyisoprene emulsion having a weight average molecular weight of 104˜105, pH of 6.0˜7.0, viscosity of 5˜20 cp (25° C.), solid content of 30˜50%, and colloidal particle size of 100˜200 nm. The polyisoprene emulsion thus obtained has excellent film-forming property; the latex articles made therefrom are suitable for use in the areas of medicine-hygiene, electronic industries, science and technology for national defense, and daily life.
    • 提供聚异戊二烯乳液,其由60〜100重量份的异戊二烯单体和5〜50重量份的选自苯乙烯,丙烯酸酯和有机酸的一种或多种单体通过使用自由基乳液聚合 在乳化剂和引发剂的存在下,所述聚异戊二烯乳液的重均分子量为10 -4〜10 5,pH为6.0〜7.0,粘度为5〜20cp(25℃),固体 含量30〜50%,胶体粒径100〜200 nm。 由此获得的聚异戊二烯乳液具有优异的成膜性; 其制成的乳胶制品适用于医药卫生,电子工业,国防科技和日常生活等领域。
