    • The invention relates to an amphiphilic block copolymer having an increased speed of water adsorption. The non-water soluble copolymer, having a hydrophilic middle block and hydrophobic endblocks, has a high rate water transmission and/or permeation. The increase in rate is due to neutralization, or partial neutralization of the hydrophilic block of the copolymer. Furthermore, the absorption rate can be controlled by the extent of the neutralization. Another aspect of the invention is the use of co-monomers and/or additives to further increase or tailor the water absorption properties. The use of additives and comonomers is also shown to enhance the processability of the disclosed polymer composition.
    • 本发明涉及具有增加的水吸附速度的两亲嵌段共聚物。 具有亲水性中间嵌段和疏水性端嵌段的非水溶性共聚物具有高速率的水透过率和/或渗透率。 速率的增加是由于中和或部分中和共聚物的亲水嵌段。 此外,吸收率可以通过中和程度来控制。 本发明的另一方面是使用共聚单体和/或添加剂来进一步增加或调整吸水性。 还显示使用添加剂和共聚单体以增强所公开的聚合物组合物的可加工性。
