  An object of the present invention is to provide a polymerizable composition capable of providing antimicrobial properties to ophthalmic and medical devices relatively inexpensively with ease, and an antimicrobial composition obtained by polymerizing the polymerizable composition. A polymerizable composition for ophthalmic or medical use comprising an epsilon-polylysine having (meth)acryloyl group is provided. The content of the epsilon-polylysine having (meth)acryloyl group in the polymerizable composition is preferably about 0.1 to 99% by weight, based on the whole amount of the composition. A coating agent for ophthalmic or medical use comprising the above polymerizable composition, an antimicrobial composition for ophthalmic or medical use obtained by polymerizing the above polymerizable composition, an ophthalmic or medical device comprising the antimicrobial composition, and a contact lens comprising the antimicrobial composition are also provided.

  Crosslinked sulfonate-containing polymers may be stable in high density, monovalent brines, which may render such polymers particularly useful in drilling fluids in general and, especially, in the subclass of drilling fluids known as drill-in fluids. For example, a drilling fluid may include a crosslinked sulfonate-containing polymer dispersed in a monovalent brine having a density of about 8 lb/gal to about 20 lb/gal, wherein the crosslinked sulfonate-containing polymer comprises: reactants of a first repeating unit and a crosslinker that react to form the crosslinked sulfonate-containing polymer, wherein the first repeating unit is a sulfonic acid-containing monomer present from 50% to 99.99% by weight of the reactants, and wherein the crosslinker comprises at least two olefinic bonds.

  含交联磺酸盐的聚合物在高密度的一价盐水中可能是稳定的，这可能使这种聚合物在一般钻井液中特别有用，尤其是在称为钻进液的钻井液子类中。例如，钻井液可包括分散在密度约为 8 磅/加仑至约 20 磅/加仑的单价盐水中的交联含磺酸盐聚合物，其中交联含磺酸盐聚合物包括：第一重复单元和交联剂的反应物，它们反应形成交联含磺酸盐聚合物，其中第一重复单元是含磺酸的单体，占反应物重量的 50% 至 99.99%（按反应物重量计），其中交联剂包含至少两个烯烃键。
