摘要:This invention relates to a process for producing high molecular weight (HMW) and ultra-high molecular weight (UHMW) acrylic polymers having unique polymer tacticity and exhibiting enhanced thermal and mechanical properties. This process comprises polymerizing ethylenically unsaturated monomer in the presence of a free radical initiator that results in a “living-like polymerâ€? utilizing a multi-step approach. In conducting the process of this invention the “living-like polymerâ€? is further dissolved in a liquid carrier, wherein the said liquid carrier is a reactive diluent that can be reacted subsequently by an addition polymerization process to create a block- or multi-block, copolymer or homopolymer. This process can be progressively repeated with the same or various different reactive diluents to generate desired architecture and molecular weight polymer(s) which can be used in further processing procedures to be manufactured directly into finished articles.

摘要:A one step synthetic route of polymeric compositions of a polyolefin and inorganic network consisting of components selected from Si, Zr, Ti, is disclosed. The synthetic route combines parallel reactions of free radical polymerization to form polymer, and hydrolysis of either Si, or Zr, or Ti or both of them precursors. The network consisting of Si, Zr, Ti, is chemically bonded to or within the polymer matrix. The inorganic or organic molecules can then be polymerized under conditions effective to cause the polymerized inorganic or organic molecules into macromolecular networks. The compositions of the polymeric composites can be easily controlled by adjusting the reactant ratio and reaction rate or conditions such as temperature and pressure, wherein the inorganic compositions disperse in nanoscale within polymeric composites when their concentrations fall below moderate levels. A novel synthesis route for making polymer composites and/or polymer nanocomposites of a polyolefin and an inorganic network consisting of components selected from Si, Zr, Ti, is disclosed. The synthesis route comprises hydrolysis of either Si, or Zr, or Ti alkoxides or mixtures of these precursors within a polymer matrix in supercritical fluids.

摘要:Cross-linkable, olefinic polymers synthesized from mixtures of olefinic polymers and ethylenically unsaturated organosilane compounds, which can be grafted, by a 2-step method using thermally decomposing free radical-forming agents by heating the mixtures to a temperature of 30 DEG to 110 DEG C. below the softening temperature or the crystallite melting point of the olefinic polymers used and subsequently heating the mixtures to a reaction temperature of 10 DEG to 60 DEG C. below the softening temperature or the crystallite melting point of the olefinic polymers used. In the alternative, they can be grafted by a method involving the action of ionizing radiation with simultaneous absorption of organosilane compounds and the action of radiation. The method is suitable for producing films, sheets, fibers, panels, coatings, pipes, hollow objects, foamed materials and molded articles.

摘要:Rubber compounds may comprise: an epoxidized polypentenamer rubber (CPR) and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles. One nonlimiting example is rubber compound comprising: phr to 90 phr of a styrene-butadiene rubber (SBR), a natural rubber (NR), and/or a butadiene rubber (BR); 10 phr to 50 phr of a epoxidized CPR and/or a hydrolyzed epoxidized CPR; and 10 phr to 200 phr of a filler comprising silica particles, wherein the SBR, the NR, the BR, the epoxidized CPR, and the hydrolyzed epoxidized CPR combined equal 100 parts. Rubber compounds comprising epoxidized CPR and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles may be useful in tire compositions.

摘要:The compatibility between silica fillers and synthetic rubbers which are synthesized utilizing lanthanide-based catalyst systems, such as neodymium catalyst systems can be improved by terminating the polymerization with a vinyl silane terminating agent. In doing so the vinyl silane is allowed to react with the polymer chain ends of the neodymium rubber to functionalize the chain ends of the polymer chains with silicon containing groups. This results in the rubber having better characteristics for utilization in tire rubber formulations, such a tire tread formulations, that exhibit improved wear characteristics and lower rolling resistance. The process for the synthesis of such functionalized polydiene rubber comprises (1) polymerizing a diene monomer in the presence of a lanthanide-based catalyst system, and (2) terminating the polymerization with a vinyl silane terminator. The functionalized polydiene rubber composition made by this method is comprised of a polydiene rubber which is functionalized at its chain ends with a silicon containing group.
