    摘要: An aqueous curing composition of a fluoroelastomer containing a fluoroelastomer, a fluororesin, a curing agent, which further contains a surfactant which leaves 0.3 wt. % or less of a decomposition residue after being heated at 300° C. for 30 minutes and/or a polar solvent having a boiling point of 300° C. or less and a surface tension of at least 30 dyne/cm at room temperature. When a coating film is formed from this aqueous composition, a large amount of the fluororesin contained therein can be bled up on the surface of the coating film. Thus, the durability and non-tackiness of the coating film can be improved.

    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.
