Abstract: A modified polymer body 1 has a polymer body 2 composed of a polymer material containing a carbon-carbon double bond and first binding parts 3 and second binding parts 4 bound to the surface of the polymer body 2. The first binding parts 3 are such that an organic group 6 having a functional group is bound via an isocyanuric acid skeleton 5 to the surface of the polymer body 2. The second binding parts 4 are such that an organic group 7 having a functional group is directly bound to the surface of the polymer body 2 without interposing an isocyanuric acid skeleton 5.

Abstract: Butadiene copolymers are brominated using certain quaternary ammonium tribromides as the brominating agent in a first step, and then with elemental bromine in a second bromination step. The bromination process proceeds easily under mild conditions, and produces a brominated product that has excellent thermal stability. The bromination proceeds to high conversions in shorter reaction times, when the bromination is performed using only the first bromination step.

Abstract: A block copolymer including a block of residues of a low surface tension (meth)acrylate monomer; a block of residues of a monomer free of hydroxyl group and amine group residues; and, optionally, a third block of residues of a monomer free of hydroxyl groups and amine groups. The first, second and third blocks are made of different residues from each other and the block copolymer has a polydispersity index of less than 2.5.

Abstract: Blocky chlorinated polyolefins are disclosed as compatibilizers of PVC and/or CPVC resins with polyolefin elastomers. The blocky chlorinated polyolefins facilitate the dispersion of the elastomers as a dispersed phase with the proper size for impact modification of the PVC and/or CPVC. The blocky chlorinated polyolefin provides better adhesion between the elastomer and the PVC and/or CPVC providing better physical properties such as impact strength as measured by Notched Izod and variable height impact testing (VHIT) than did the randomly chlorinated polyolefins, often used as processing aids and as impact modifiers in PVC or CPVC. The differences in properties achieved with blocky chlorinated polyolefins versus randomly chlorinated polyolefins are attributed to the individual blocks of the blocky polyolefin being compatible (and/or co-crystalizable) with either the polyolefin elastomer or the PVC/CPVC resulting in better adhesion between phases.
