20080242756 | DENTAL COMPOSITE RESIN FOR CORE BUILD-UP - To provide a dual curing type composite resin for core build-up having improved curing property by chemical polymerization with improved mechanical strength of a cured body under the condition of no light irradiation and with a shortened setting time, the composite resin is composed of a first component including a (meth)acrylate polymerizable resin and an organic peroxide, and a second component including (meth)acrylate polymerizable resin and a reducing agent, a photopolymerizaton initiator and a filler are included in the first component and/or the second component, and oxide powder of a Group II element in the periodic table having an average particle diameter of 1 μm or less is blended in the first component and/or the second component. | 10-02-2008 |
20140135414 | PREPARATION OF POLYMERIZABLE COMPOSITIONS - Processes for modifying the viscosity of medically useful polymerizable compositions are described. The processes are carried out by providing an oxygen-free fluid composition comprising one or more polymerizable monomers and subsequently irradiating the composition with a controlled dose of high-energy radiation sufficient to effect a desired viscosity increase. Compositions produced via these process are also disclosed. | 05-15-2014 |

20130225712 | MANGANESE CATALYZED PHOTOPOLYMERIZATION OF FLUORINATED MONOMERS - The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations. | 08-29-2013 |
20150018446 | ORGANOCATALYZED PHOTOREDOX MEDIATED POLYMERIZATION USING VISIBLE LIGHT - The present invention is directed to method of forming a polymer comprising exposing a mixture comprising an organic pre-polymer, an organic photoredox catalyst, and an organic initiator to a source of visible or near-infrared light under conditions and for a time sufficient to polymerize the organic pre-polymer, and polymers and articles derived therefrom. | 01-15-2015 |
