  • Patent number: 8097687
    Abstract: The invention provides compositions of matter, methods of their synthesis, and methods of their use in polymerization reactions. The compositions include polyfunctional initiators used to make star polymers when polymerized with monomers. The polyfunctional initiators are synthesized out of a multifunctional core with at least two functional groups and two or more initiator units bonded to the functional groups. The initiator units have two electron-withdrawing groups bonded to a central carbon atom and an azo group between the central carbon atom and the functional group. The polyfunctional initiators are particularly effective because when they decompose to form the radical core of a star polymer, the electron-withdrawing groups prevent the corresponding radical from forming any linear polymer contamination and only desired star polymers result.

  • Patent number: 7534843
    Abstract: The invention is a two part polymerizable composition comprising in one part an organoboron compound capable of forming free radical generating species amine complex and in the second part one or more compounds capable of free radical polymerization and a cure accelerator comprising a) at least one compound containing a quinone structure or b) at least one compound containing at least one aromatic ring and one or more, preferably two substituents on the aromatic ring selected from hydroxyl, ether and both, where there are two substituents they are located either ortho or para with respect to one another and a peroxide containing compound. The second part may further contain an agent capable of causing the organoboron compound to form free radical generating species upon contacting the two parts. The first part may further comprises one or more compounds capable of free radical polymerization. This facilitates formulating compositions that have commercially desirable volumetric ratios of the two parts.

  • Patent number: 7514511
    Abstract: Free radical polymerization process for preparing polymers with low polydispersity index and polymers obtained thereby. The process includes polymerizing at least one reactive monomer with at least one initiator and at least one ionic liquid (serving as solvent) to obtain polymers having a low polydispersity index of less than 1.5, wherein the reactive monomer is a nitrogen-containing monomer. In addition, the free radical polymerization processes have reaction time within 3 hours.

  • Publication number: 20090023876
    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.

  • Patent number: 7365115
    Abstract: An anti-reflective coating film is formed by applying on a chemically amplified photoresist film an anti-reflective coating composition comprising an alkali-soluble fluorine-containing polymer, an acid, an amine and a solvent capable of dissolving these components and having a pH of 7 or less. The formed anti-reflective coating film can serve to prevent multiple reflections within the photoresist film, increase the amount of reduction in thickness of the photoresist film upon development with a developer after exposure, and form a pattern having a rectangular cross-sectional pattern and not having T-top or round top.
