  • Publication number: 20120130009
    Abstract: Vulcanizates with desirable properties can be obtained from compounds incorporating polymers that include hydroxyl group-containing diphenylethylene-type functionalities. The functionalities can be incorporated by using any or all of appropriate initiators, monomers and optional terminating compounds. Such polymers exhibit excellent interactivity with both conventional and non-conventional fillers.

  • Publication number: 20110311639
    Abstract: Described is a direct method for the fabrication of resorcinarene nanocapsules by photopolymerization of compounds of formula (I), such as resorcinarene tetraalkene tetrathiol (RTATT), in the absence of any template or preorganization. Further, by varying the polymerization media, a variety of other polymeric architectures like lattices, fibrous networks, and nanoparticles were obtained. The morphology and structure were characterized by transmission electron microscopy, energy dispersive spectroscopy, scanning electron microscopy, dynamic light scattering, infrared and nuclear magnetic resonance spectroscopy. These morphologically distinct resorcinarene polymeric architectures contain residual thiol and ene functional groups offering potential functionalization opportunities.

  • Publication number: 20110130511
    Abstract: A modified natural rubber particle having carbon-carbon double bonds assigned to multifunctional vinyl monomers graft-copolymerized onto the surface of the modified natural rubber particle, which is prepared by graft-copolymerization of multifunctional vinyl monomers having two or more carbon-carbon double bonds onto natural rubber particles or deproteinized natural rubber particles. One of the methods for producing a modified natural rubber particle includes the steps of: forming inclusion complex of the multifunctional vinyl monomers having two or more carbon-carbon double bonds with a guest-protecting agent to protect at least one of the double bonds of the multifunctional vinyl monomers; graft-copolymerizing the resulting inclusion complex onto natural rubber particles or deproteinized natural rubber particles; and deprotecting the protected double bonds by removing the guest-protecting agent from the obtained graft-copolymer.
