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 polymer†utilizing a multi-step approach. In conducting the process of this invention the “living-like polymer†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: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.
