  • Publication number: 20100216954
    Abstract: [Problems] Thermoplastic resins have various problems such as enhancement in strength and improvement in toughness and heat resistance and copolymerization with monomers or oligomers and grafting have been carried out to solve the problems. Although graft polymerization with macromonomers has been carried out as a method for solving the problems, it is still expected to develop a modification technique for attaining better performance and resins produced by the technique. [Means for Solving Problems] A thermoplastic resin obtained by addition polymerization of an addition-polymerizable monomer, characterized by being modified by copolymerization with a vinyl polymer (I) which bears at least one group having a polymerizable carbon-carbon double bond at each of at least two molecular ends and which has a weight-average molecular weight (Mw)/number-average molecular weight (Mn) ratio of less than 1.8.

  • Patent number: 7763688
    Abstract: The present invention describes the synthesis of solvent soluble copolymers containing multiple unsaturations. These copolymers contain reactive vinyl groups, which can be further reacted in a second stage polymerization. The process involves copolymerization of a vinyl monomer with an inclusion complex of a monomer having multiple unsaturations and a cyclic macromolecular compound to yield soluble polymers. These polymers may be cast into films, membranes or may be converted in micro or nanoparticles and then crosslinked in a second step polymerization.

  • Publication number: 20100160561
    Abstract: The present invention is directed to copolymers, which are polymerization products of: (i) a monomer having alpha-olefinic functionality; (ii) a monomer different from (i) having active hydrogen functionality; and (iii) a monomer different from (ii) having acrylic functionality. The molar ratio of the monomer (i) having alpha-olefinic functionality to the monomer (iii) having acrylic functionality is less than 1:1, and the conversion of the monomer (i) having alpha-olefinic functionality during polymerization is greater than 90%. When monomers having methacrylic functionality are used to prepare the copolymer, the molar ratio of the monomer (iii) having acrylic functionality to the monomers having methacrylic functionality is greater than 2:1. Also disclosed are curable film-forming compositions comprising the copolymers.

The invention also provides methods for reducing the loss of volatile organic compounds (VOCs) from oil storage containers using multifunctional, multipolymer surfactants. The multifunctional, multipolymer surfactants are characterized by a hydrophobic part and a hydrophilic part. The hydrophobic part of the polymer surfactants includes functionalities that impart a polarity of greater than 0 Debye to the hydrophobic part. The polymer surfactants are further characterized by molecular weights that are above their entanglement weights. The result is polymer surfactants and their continuous composition surfactant-thickener mixtures with demulsifying characteristics.
