Abstract: A pattern article comprising a copolymer having polymerized units derived from a cleavable crosslinking monomer, to which a pattern is imparted by the release of incipient acid from a thermal acid generator or photoacid generator. The selective release of the acid provides a pattern of high crosslink density and low crosslink density as result of the incipient acid cleaving a portion of the crosslinks.

Abstract: The invention is generally related to a soft contact lens which comprises a hydrogel lens body and a coating of a hydrophilic copolymer thereon and to a method for producing the same. The hydrogel lens body comprises or is made of a polymeric material having 1,2- and/or 1,3-diol moieties, and the hydrophilic copolymer comprises arylborono-containing repeating units each having a boronic acid group. The coating is covalently-attached to the hydrogel lens body through cyclic boronic ester linkages each formed between one boronic acid group and one 1,2-diol or 1,3-diol group. The soft contact lens has a surface lubricity higher than the surface lubricity of the lens body.

Abstract: Provided are a method for producing a multibranched polymer that can produce a multibranched polymer having a narrow molecular weight distribution in a one-pot procedure and the multibranched polymer. A method for producing a multibranched polymer includes the step of polymerizing a first vinyl monomer having a polymerization-initiating group in an α-position of a vinyl bond and a second vinyl monomer free of polymerization-initiating group in an α-position of a vinyl bond by a living radical polymerization.

Abstract: In this invention, polyimidazole ligands (PILs) incorporating pendant imidazole moieties for nanocrystal binding and either sulfonatebetaine, carboxybetaine, or phosphocholinebetaine moieties for water-solubilization have been developed. Greatly enhanced stability of nanocrystals (both over time and in wide pH range) was achieved by incorporating multi-dentate imidazole moieties which provide strong coordination of the ligand to the nanocrystal surface and prevent aggregation of nanocrystals. Synthesis of betaine PILs was developed by modifying the synthesis of recently developed PEG containing poly imidazole ligands (PEG PILs). These nanocrystals are compact, water soluble, and biocompatible.
