This invention presented herein is a hybrid batting and sliding glove that will reduce the number of hand injuries associated with sliding head first into a base in the sports of baseball and softball. There are three key features. The Tendon Feature gently pulls the hand back keeping the fingers off the ground and into a safer position for sliding. The wrist closure feature keeps the wrist from hyperextending. The figure feature component keeps the fingers together.

Hybrid batting and sliding glove

A blend of polyketone and polycarbonate polymers is presented. The polymer blend is produced by blending polyketone polymer, polycarbonate polymer, and a reactive graft compatibilizer. The a reactive graft compatibilizer compatibilizes the blend.

Compatibilized polyketone polymer blend

Improved compositions comprise miscible polymer blends of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with a styrene/acrylonitrile copolymer rich in acrylonitrile.

Miscible polyketone polymer blend

Reinforced polymer blends with improved mechanical properties are produced from a blend of a polyketone polymer and an uncured phenolic-based novolac resin, reinforced with glass fibers.

Reinforced polyketone polymers

A miscible polymer blend composition may be formed by combining a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with a styrene/vinyl phenol copolymer containing at least about 20 mole percent vinyl phenol units.

Polymer compositions comprising linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon filled with mica are prepared without the use of a coupling agent.

Polyketone compositions

A miscible polymer blend comprising polyketone and phenolic-based novolac polymers is provided. These blends have as a primary advantage a Tg which can be manipulated so as to produce desirable properties. A process for producing these blends and articles of manufacture produced therefrom are also disclosed.

Polyacetal polymer blends

Polymer compositions comprising an intimate mixture of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and a poly(vinylidene fluoride) exhibit improved barrier properties. The poly(vinylidene fluoride) is also useful in a method of reducing the water vapor transmission rate of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon.

Polymer with improved barrier properties

Improved polymer blends comprise (a) a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, (b) a polymeric polyamide, (c) a maleated, partially hydrogenated elastomeric block copolymer, and optionally (d) an acidic polymer of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid wherein, optionally, a portion of the carboxylic acid groups have been neutralized with non-alkali metal. The blends demonstrate a good balance of strength and toughness.

Polymer blends

Filled polymer compositions comprising a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and lesser amounts, on a volume basis, of a mineral wool fiber.
