摘要： Disclosed are polymerization initiators as may be utilized for addition of polymers to a substrate surface. The initiators are azo-based initiators that include multi-functionality through addition of multiple anchoring agents to an inner azo group. Disclosed polymerization initiators can be utilized to form high density and high molecular weight polymers on a surface such as a particulate surface. Formed materials can be beneficial in one embodiment in fracking applications, providing composite proppant/polymer materials that can prevent leakage of polymers from a subterranean geologic formation.

摘要： A radical polymerization method that enables synthesis, at a high conversion rate, of polymers having a relatively uniform molecular weight and is applicable to various monomers, and an apparatus used for the method. A reaction solution containing monomer and initiator is continuously or intermittently circulated in the apparatus and is heated in a heating-initiation unit to a predetermined temperature simultaneously across a radial direction of a cross section of the flow path whereby the initiator located in a particular volume of the reaction solution is cleaved all at once. The apparatus includes a heating medium production unit 10, a heating medium-reaction solution mixing unit 20, a cooling unit 30, and a recovery unit 40 for a reaction mixture, all communicatively connected by the flow path and optionally a heating reaction unit 60, a cooling unit 70, and a recovery unit 80, all communicatively connected by the flow path.

摘要： The present invention provides a method for continuous polymerization of ethylenically unsaturated monomers in a water-in-oil inverse emulsion under adiabatic conditions without the need for external cooling during the polymerization. The method comprises neutralizing a monomer composition comprising at least one acidic vinyl monomer with a base in an aqueous medium comprising water and water ice to form an aqueous monomer solution therefrom; homogenizing and degassing to form an inverse monomer emulsion; initiating polymerization; passing the inverse emulsion through a tube reactor without cooling, and flash evaporating a portion of the water from inverse emulsion to cool and concentrate the resulting polymer-containing inverse emulsion. During neutralization, the aqueous medium comprises an amount of water ice sufficient to maintain a temperature of 30° C. or less, and the polymerization is initiated by adding a free-radical polymerization initiator to the emulsion prior to passing the emulsion through the tube reactor.
