Polymer compositions comprising nylon and a halogenated polymer. In one aspect, the present invention includes a polymer composition comprising about 1% to about 99% by weight of nylon and about 1% to about 99% by weight of halogenated polymer, wherein the combined percent of the nylon and the halogenated polymer is at least about 80 percent. In another aspect, the present invention includes a polymer composition consisting essentially of nylon and halogenated polymer. In yet another aspect, the present invention includes an article comprising a polymer made by a process comprising the steps of providing nylon and halogenated polymer materials; melting the nylon and halogenated polymer materials; and forming the article from the melt of nylon and halogenated polymer materials. |

DETAILED DESCRIPTION The present invention provides polymer compositions and polymer articles having optimized mechanical and friction properties.
All embodiments of the present invention comprise nylon and at least one halogenated polymer to yield polymer compositions having a combination of desired properties such as strength, toughness, and low friction coefficients.
In addition, the polymer compositions of the present invention provide significant cost savings over halogenated polymers (e.
g.
, TEFLON) alone, which are typically much more expensive than nylon.
Moreover, the polymer compositions of the present invention are amenable to a wide variety of processes such as, for example, injection molding, extrusion (e.
g.
, blown film extrusion, cast film extrusion, sheet extrusion, etc.
), blow molding, calendering, sheet forming, stamping, casting, and spinning.
In contrast, polymers consisting only of halogenated polymers such as TEFLON may not be suited to some of these forming processes.
The inventors have surprisingly found that polyamides and halogenated polymers can be combined to produce a product having a uniform composition and optimum properties.
In one aspect, the present invention includes a polymer composition comprising about 1% to about 99% by weight of nylon and about 1% to about 99% by weight of halogenated polymer, wherein the combined percent of nylon and halogenated polymer is at least about 80% of the polymer composition.
In another embodiment, the combined percent of the nylon and halogenated polymer is at least about 85% of the polymer composition.
In another embodiment, the combined percent of the nylon and halogenated polymer is at least about 90% of the polymer composition.
In another embodiment, the combined percent of the nylon and halogenated polymer is at least about 95% of the polymer composition.
In yet another embodiment, the combined percent of the nylon and halogenated polymer is at least about 98% of the polymer composition.
Other embodiments are defined by the ratio of nylon and halogenated polymer in the polymer composition
