LATEX COMPRISING WATER AND A STYRENIC BLOCK COPOLYMER AND A PROCESS FOR PREPARING ARTICLES THEREFROM
摘要：
Articles with enhanced tensile strength and comfort are prepared from a latex comprising water and a styrenic block copolymer, wherein the styrenic block copolymer has 2 or more poly(vinyl aromatic) blocks and at least one block of polymerized conjugated diene wherein the styrenic block copolymer has a weight average molecular weight of 150,000 to 250,000, the poly(vinyl aromatic) blocks have a weight average molecular weight ranging from 9,000 to 15,000, and the content of poly(vinylaromatic) blocks in the styrenic block copolymer ranges from 8 to 15% wt, based on the total styrenic block copolymer, by a process which comprises coating a surface with the latex to obtain a film, wherein the latex comprises a vulcanising agent. The invention also provides a latex comprising such a styrenic block copolymer and a vulcanising agent, as well as a styrenic block copolymer that is particularly suitable for use in such a latex.
摘要（中）：

具有增强的拉伸强度和舒适性的制品由包含水和苯乙烯嵌段共聚物的胶乳制备，其中苯乙烯嵌段共聚物具有2个或更多个聚（乙烯基芳族化合物）嵌段和至少一个聚合共轭二烯嵌段，其中苯乙烯嵌段共聚物具有 重均分子量为15万〜25万，聚（乙烯基芳香族）嵌段的重均分子量为9000〜15000，苯乙烯系嵌段共聚物中的聚（乙烯基芳香族）嵌段的含量为8〜15重量％ ，基于总苯乙烯嵌段共聚物，通过包括用胶乳涂布表面以获得膜的方法，其中胶乳包含硫化剂。 本发明还提供了包含这种苯乙烯嵌段共聚物和硫化剂的胶乳，以及特别适用于这种胶乳的苯乙烯嵌段共聚物。
