  Gypsum scale inhibitors useful under wet flue gas desulfurization (FGD) scrubber temperature and pH conditions. The gypsum inhibitors advantageously prevent or minimize gypsum scale formation and crystal growth in mist eliminator wash water and in the scrubber internals. Specific inhibitors contemplated include copolymers of modified acrylic acid/acrylamide; acrylic acid/vinyl acetate; acrylic acid/maleic anhydride; acrylic acid/acrylate ester; and combinations thereof. In addition, gypsum scale inhibitors comprising phosphonate-polymer blends of hexamethylene diamine tetra (methylene phosphonic acid) salts and polymaleate, poly(acrylic acid/ethylacrylate), poly(acrylic acid/N-methoxypropyl acrylamide/acrylamide), poly(acrylic acid/N-propyl acrylamide/acrylamide), and combinations thereof are also contemplated.

  A resin composition which, in forming a fine pattern by a heat treatment of a resist pattern formed by using a photoresist, can be applied onto the resist pattern, can cause the resist pattern to smoothly shrink by heat treatment, and can be easily washed away by a treatment with an alkaline aqueous solution, and a method for efficiently forming a fine resist pattern using the resin composition are provided. The resin composition comprises a resin containing a hydroxyl group, a crosslinking component, and an alcohol solvent containing water in an amount of 10 wt % or less for the total solvent, wherein the alcohol in the alcohol solvent is a monovalent alcohol having 1 to 8 carbon atoms.

  A low water content soft lens for eye is provided, which includes a layer made of an acidic polymer and a basic polymer on at least a part of a surface of a base material containing a polysiloxane compound. Adhesion of the lens to the cornea during wear, which has hitherto been regarded as a problem in a conventional low water content soft lens for eye, can be reduced or avoided when using the low water content soft lens.

  Disclosed is a medical device having an elastic modulus of 100 kPa or more and 2,000 kPa or less, a water content of 10% by mass or less, a tensile elongation of 50% or more and 3,000% or less, and a dynamic contact angle (advancing angle) relative to a borate buffer of 80° or less. The present invention can significantly reduce or avoid a phenomenon of adhesion to a surface when contacted with a surface outside or inside the body, which has hitherto been regarded as a problem in a conventional medical device.

  本发明公开了一种医疗器械，其弹性模量为100 kPa或更高，2,000 kPa或更低，水含量为质量的10%或更低，拉伸延伸率为50%或更高，3,000%或更低，相对于硼酸缓冲液的动态接触角（前进角）为80°或更低。本发明可以显著减少或避免与体内外表面接触时粘附的现象，这在传统医疗器械中一直被视为问题。
