摘要： This invention relates to anionically polymerized block copolymers comprised of at least one block of polyethylene and at least one block of a polymerized cyclic siloxane monomer wherein said cyclic siloxane monomer contains at least one functional group containing a fluorocarbon substituent, e.g., 2,4,6-tris(3,3,3-trifluoropropyl)-1,3,5-trimethylcyclotrisiloxane. The fluoro-functionality may instead be introduced into the polymer by using said siloxane monomer to end cap the polymer. These copolymers can be used in extruded release coating films prepared by blending the copolymer with a film grade polymer. They can also be used to modify surface adhesion, promote flow in polymer processing or coat a polymeric surface to impart properties such as a barrier to water vapor transmission, or solvent resistance.

摘要： In the production of "inside-out" star polymers where a first polymer lithium chain is formed, coupled and thereafter additional monomer is introduced to produce the "out" polymer chains, improved control over the second polymerization is obtained by coupling with a mixture of a monoalkenyl-substituted aromatic compound and a polyalkenyl-substituted aromatic compound. For example, a mixture of divinylbenzene and styrene can be used. In another embodiment, an ether is introduced after completion of the first polymer chain formation. The presence of the ether also improves the second stage chain formation. Utilization of both the mixed coupling agents and the ether, preferably a diether such as 1,2-diethoxyethane gives the greatest control over the uniformity of the second stage polymerization, making possible the production of narrower molecular weight distribution polymer having no indication of bimodal distribution. The narrow molecular weight distribution is advantageous in many applications.

摘要： A thermoplastic elastomer produced without a hydrogenation step is functionalized utilizing a free radical initiator and a functionalizing monomer having at least one point of unsaturation. The base polymers can be produced by copolymerizing an &agr;-olefin capable of producing an amorphous backbone with a comonomer which provides a “hook” for grafting to with a living polystyrene chain. Another method is to copolymerize an &agr;-olefin monomer system capable of producing an amorphous backbone with a comonomer containing a functional group from which an anionically polymerizable monomer is grown from the backbone. A third method involves copolymerizing an &agr;-olefin monomer system capable of giving an amorphous backbone with an olefin-terminated polystyrene comonomer. In a less preferred embodiment a conventional EPDM polymer can be metallated and a monoalkenyl aromatic compound anionically polymerizable monomer grown from the backbone.
