摘要： A copolymer composition that includes a silicone copolymer, methods of making the composition, and articles that include the composition, wherein the copolymer composition includes a silicone copolymer having a backbone composition that includes: silicone segments in an amount of 5 wt-% to 40 wt-%, based on the total weight of the silicone copolymer; hydrophilic segments in an amount of 40 wt-% to 75 wt-%, based on the total weight of the silicone copolymer; and reinforcing segments in an amount of 5 wt-% to 30 wt-%, based on the total weight of the silicone copolymer, wherein the reinforcing segments are derived from the reaction of one or more chain extenders with one or more multi-functional isocyanates, multi-functional carboxylic acids, multi-functional anhydrides, multi-functional esters, and/or multi-functional acid halides; wherein the silicone segments, hydrophilic segments, and reinforcing segments are connected through urea, urethane, amide, and/or oxamide linkages; wherein the hydrophilic segments and the reinforcing segments are present in a weight ratio of 1.8:1 to 8:1; and the hydrophilic segments and the silicone segments are present in a weight ratio of 1.3:1 to 4.5:1.
摘要翻译：包含有机硅共聚物的共聚物组合物，制备所述组合物的方法以及包含所述组合物的制品，其中所述共聚物组合物包含具有主链组成的有机硅共聚物，所述主链组成包括：基于硅氧烷共聚物的总重量，5重量％至40重量％基于硅氧烷共聚物的总重量，40重量％至75重量％的量的亲水性链段; 和基于硅酮共聚物的总重量为5重量％至30重量％的量的增强链段，其中增强链段衍生自一种或多种扩链剂与一种或多种多官能异氰酸酯，多官能羧酸，多官能酸酐，多官能酯和/或多官能酰基卤; 其中有机硅链段，亲水链段和增强链段通过脲，氨基甲酸乙酯，酰胺和/或草酰胺键连接; 其中亲水片段和增强片段以1.8:1至8:1的重量比存在; 并且亲水性链段和硅氧烷链段以1.3:1至4.5:1的重量比存在。
