  • Publication number: 20120157701
    Abstract: A process for preparing siloxy carboxylates is characterized by reaction of C2-C10-monocarboxylic acids with halosiloxanes of the general formula (I), Hal-(SiR2—O)x—SiR3??(I) in which Hal is the same or different and is fluorine, chlorine, bromine or iodine, R is hydrogen, C1-C10-alkyl or C6-C14-aryl and x is an integer from 1 to 20, to form hydrogen halide in the presence of an auxiliary base, in which the auxiliary base forms, with the hydrogen halide, a salt which forms two immiscible phases with the siloxy carboxylate or the solution of the siloxy carboxylate in a suitable solvent and is removed by a liquid-liquid separation. The process enables simple and economically viable preparation of siloxy carboxylates.

  • Publication number: 20120004380
    Abstract: Crosslink agents used to copolymerize at least one hydrophilic monomer with at least one lens monomer typically used to prepare polymeric materials for ophthalmic lenses. The crosslink agents have a relatively high selectivity for the hydrophilic monomer and limited reactivity with the crosslink agent used to polymerize the lens monomer. Accordingly, the invention is also directed to a hydrophilic crosslinked polymer that comprises at least two monomeric units and at least two different crosslink units. The use of the dual crosslink system provides an improved means to control the final chemical, physical and structural characteristics of the resulting polymer.
