A grip member and a method of making such a grip member including at least a polymerized region with two or more polymers. The first and second polymers cooperate to each form a portion of the top surface of the region. The region may be combined with a substrate to form a sheet. The sheet may be formed into a grip interface having any of a number of shapes including a panel shape. In the case of a panel shaped grip interface, the panel can then be attached to an underlisting sleeve to form the grip. Some versions of such a grip reduce impact shock and provide a feeling of tackiness in the manner of a spirally wrapped polyurethane-felt grip while allowing the use of multiple colors being polymerized together. The grip may be easily installed onto a golf club shaft and may further accommodate the use of polymers including various different characteristics including level of tackiness or durometer.

A polymer sheet includes a polyurethane core. The polyurethane core has a first major surface and a second major surface opposite the first major surface. The polymer sheet can have at least one functional layer overlying a major surface. The polymer sheet has a thickness t.sub.PS. The polyurethane core has a thickness t.sub.PC. In embodiments t.sub.PC can be at least 0.3 t.sub.PS. The polyurethane core can have at least one of the following property: (i) a Scratch Resistance Rating, as further described herein, of not greater than about 10 wt %, (ii) an elongation at break of at least 200%, (iii) a tensile strength at break of at least 0.3 MPa, (iv) a loss of tensile strength of not greater than about 30% when exposed to UV light according to standard SAE J1960 (Rev. August 2003).
The polymer sheet can be used for gaskets or bonding tapes.

A water-soluble film (WSF) system comprises at least one active material embedded/entrapped in the film so as to provide precise and desired release of the at least one active material therefrom. The at least one active material includes detergents, enzymes, softeners, perfumes, pesticides, fungicides, active ingredients, dyes, pigments, hazardous chemicals, active agents for cleaning laundry, dishes, floorings, walls, furniture, fluffs, pulp, and combinations thereof. Online and offline processes can be used for the manufacture of multi-layered WSFs with or without liners. The WSFs can be formed in desired shapes to selectively entrap interacting/non-interacting materials and combinations thereof. The process also provides options for the use of a wide range of raw materials, liners such as paper, film, foil, fabric, etc.
