摘要： Water-soluble polymers comprising an N-vinyl amide such as an N-vinyl lactam are found to be useful in processes wherein the polymer is introduced into a subterranean wellbore.Polymers useful in the recovery of natural resources are prepared by polymerizing an N-vinyl lactam by free radical initiation with polymerization conducted in an aqueous solution polymerization medium preferably containing a mixture of dissolved electrolytes, or in a polymerization medium consisting essentially of a tertiary alkanol. Copolymers of such N-vinyl lactams with unsaturated amides, and terpolymers prepared by polymerizing an N-vinyl lactam and an unsaturated amide with a selected termonomer compound are also useful when prepared by these methods. The invention also broadly encompasses utilizing a water-soluble polymer comprising at least one of a hydrophilic vinyl-containing sulfonate, phosphonate or ester and/or a hydrophilic N-vinyl lactam for applications under hostile conditions.

摘要： This invention relates generally to fibers and fabrics prepared using crystalline propylene polymer compositions comprising both propylene homopolymer and propylene copolymer. The propylene polymer compositions are prepared using at least one metallocene catalyst system in a polymerization process that involves the initial homopolymerization of propylene followed by the copolymerization of propylene with a small amount of comonomer. Fibers prepared with these propylene polymers are significantly more elastic and fabrics prepared with these polymers have a significantly broader bonding window which allows for more easy processing compared to fibers and fabrics prepared from known propylene polymers.
