摘要：
The invention relates to an olefinically unsaturated radial styrenic block copolymer of the general formula: A-B-Y-(B-A)n wherein - each A is independently a polymer block composed for at least 90 mol.% of an alkenyl aromatic hydrocarbon - the content of A by weight of the total weight of the polymer (PSC) is in the range of 8-13% - Y is the remnant of a coupling agent having a functionality greater than 2 - the degree of branching (DoB) is n+1, wherein n is an integer from 2 to 5, preferably 2 to 4 - each B is independently a polymer block composed for at least 90 mol.% of one or more conjugated dienes - the styrenic block copolymer has a coupling efficiency (CE) of at least 90% - each A block independently has a weight average molecular weight (MW A) ranging from 9,000 to 15,000, and - each B Block independently has a weight average molecular weight (MW B) ranging from 75,000 to 150,000 to an artificial latex comprising the same and dipped goods made therefrom.本發明係關於一種以下通式之烯系不飽和徑向苯乙烯嵌段共聚物:A-B-Y-(B-A)n其中:A各自獨立地為至少90莫耳%係由烯基芳香烴組成之聚合物嵌段;該聚合物總重量中的A含量(以重量計)(PSC)係在8至13%範圍內;Y為具有大於2之官能度之偶聯劑之殘留物;分支度(DoB)為n+1,其中n為自2至5之整數,較佳係2至4;B各自獨立地為至少90莫耳%係由一或多種共軛二烯組成之聚合物嵌段;該苯乙烯嵌段共聚物具有至少90%之偶聯效率(CE);A嵌段各自獨立地具有介於9,000至15,000範圍內之重量平均分子量(MW A),且B嵌段各自獨立地具有介於75,000至150,000範圍內之重量平均分子量(MW B);關於一種包含該烯系不飽和徑向苯乙烯嵌段共聚物之人造乳膠及由其製得的浸漬物品。
