Multi-layered golf balls having at least one layer made of a foamed silicone composition are provided. Multi-layered golf balls having at least one layer made of non-foamed silicone elastomer composition also are provided. For example, three-piece, four-piece, and five-piece golf balls containing different core and cover structures can be made. The foamed silicones have good thermal stability and durability without sacrificing resiliency. The non-foamed silicone elastomers have high elongation, tensile strength, chemical/fluid-resistance, and weatherability properties. These compositions can be used to form any layer, for example, core, intermediate, or cover, in the golf ball.

The present invention provides a polyolefin composition, said composition comprising a terpolymer comprising a cross-linkable polyolefin comprising hydrolysable silane groups and a polar comonomer, the polyolefin composition further comprising a cross-linking catalyst and a silicon containing compound.

An aqueous composition that can be used to provide release properties to adhesive tape substrates can be applied at coating weights far less than those required in previously available compositions containing the same or similar release polymers. Inclusion of small amounts of a superwetter results in improved coatability and reduced amounts of sound generated during the process of releasing an adhesive tape from its roll.

Provided are novel cross-linked polymers and their use in various materials, including packaging films and injection molded articles. These polymers, which comprise certain hydroxyl-containing crosslinking compounds, as well as optionally adjuvants, show improved creep resistance when compared to conventional ethylene acrylic or methacrylic acid copolymers and their ionomers.
