摘要:
A polymer useful in forming coatings for articles is provided. The polymer is an acrylic copolymer formed as the reaction product of a plurality of monomers which include an alkyl (meth)acrylate, a quaternary amine (meth)acrylate, a hydroxyalkyl (meth)acrylate, an N-vinyl lactam, an ethylenically unsaturated carboxylic acid, and a fluorinated (meth)acrylate. The polymer is formed in the presence of surfactants, preferably by sequential polymerization of two separate monomer mixtures. To form a coating, the polymer is blended with an elastomeric material such as nitrile rubber latex. The resulting coating is useful both as a print coating for substrates used with ink jet printers and as a coating for rubber articles.

ClO4 with other aliphatic, unsaturated monomers. The invention also relates to a method for production of said polymers. Said polymers can also be produced by graft copolymerisation of a substrate, whereby a covalently bonded coating is obtained on the substrate surface. The inventive antimicrobial polymers can be used inter alia as microbiocidal coatings on hygiene articles or in the medical field and in paints or protective coatings.

Described are articles having a polyanhydride photochromic coating. The coatings exhibit a Fischer microhardness of from 50 to 130 Newtons per mm and desirable photochromic properties, i.e., the formation of darker activated colors and faster rates of photochromic activation and fade when irradiated with ultraviolet light. Also described are polyanhydride photochromic articles.
摘要:
A coating composition for forming a water-resistant coating on fiber-reinforced articles such as rods or cables. The composition comprises an aqueous solution of a superabsorbent water-soluble polymer, a viscosity modifying agent, and optionally a lubricant. The coating formed by applying the composition effectively prevents the treated surface from water-permeation damage by absorbing water that contacts the layer containing the superabsorbent component.
摘要:
Carbamate-functional allyl monomers and methods for making them are disclosed. The monomers, which are easy to prepare, readily polymerize with common ethylenic monomers to give low-molecular-weight resins without the need for solvents or chain-transfer agents. Coatings made from the resins should have good durability, good acid etch resistance, good mar resistance, high gloss, and high DOI.
