    摘要: The present invention relates to a process for the formation of water soluble copolymers of acrylamide and alkyl poly(etheroxy)acrylate which are finished by a dialysis process and are excellent viscosification agents. Wherein the process includes the free radical copolymerization of acrylamide monomer and alkyl poly(etheroxy)acrylate monomer in an aqueous medium under nitrogen conditions in the presence of free radical initiator at a sufficient temperature and for a sufficient time to effect copolymerization.

    摘要: The copolymerization of water soluble monomers with water insoluble monomers can be effected by using a solution of a water soluble surfactant to solubilize the water insoluble monomer. The aqueous medium containing the surfactant and water insoluble monomer is therefore a homogeneous, isotropic, transparent dispersion, into which the water soluble monomer can be dissolved and, after addition of a suitable free radical initiator, can be copolymerized to give a reaction mixture which does not phase separate, or contain substantial amounts of particulates of insoluble monomer. The copolymers which may be isolated from the reaction mixture are good viscosifiers of water and brine.

    摘要: This invention relates to a process for first preparing a free flowing finely divided powder of a neutralized sulfonated elastomer and subsequently and optionally admixing said formed powder with other agents such as fillers and oils thereby providing free flowing powders capable of being subsequently fabricated into tough elastomeric objects. The neutralized sulfonated elastomeric polymer can be converted into a free flowing finely divided powder which does not agglomerate or cold flow under ambient conditions by a variety of processes, preferably by a grinding process conducted at low temperatures. The formed powder of the neutralized sulfonated elastomeric polymer is blended with at least one chemical additive into a homogeneous mixture, wherein the chemical additive is selected from the group including fillers, polyolefinic thermoplastics, non-polar backbone process oils, lubricants or a metallic oxide and mixtures thereof. The homogeneous mixture is formed into a finished elastomeric article by conventional fabrication.
