US Classification:

473372, 473351, 473409, 219201, 219635

Abstract:

A phase transition golf ball comprises a phase transition material. The phase transition material may optionally include a microwave susceptor or an induction susceptor. The phase transition material preferably comprises an ethylene acid copolymer, or an ionomer of an ethylene acid copolymer. The performance of the phase transition golf ball, for example its hardness or compression, is adjusted by inducing a complete or partial phase transition in the phase transition material. The extent of the adjustment in performance is correlated with the extent of the phase transition. Preferably, the phase transition is reversible and repeatable and takes place at temperatures that might be achieved through the use of common household appliances. Also preferably, the phase transition material returns to its original state over an extended period, for example hours or days.

US Classification:

136251, 156 60, 156285, 1563077, 136259

Abstract:

A polymeric film or sheet comprising an ionomeric composition comprising ionomeric copolymer of an alpha olefin and about 1 to about 30 wt % of alpha,beta-ethylenically unsaturated carboxylic acid having 3 to 8 carbons, based on the total weight of the ionomeric copolymer, wherein the carboxylic acid is neutralized to a level of 1 to 100 mol %, with one or more metal ions, based on the total number of moles of carboxylate groups in the ionomeric copolymer, and wherein the ionomeric copolymer has a Melt Index of about 20 to about 300 g/10 min. The ionomeric composition preferably comprises an additive selected from the group consisting of silane coupling agent, organic peroxide, and combinations thereof. In addition, an article comprising an interlayer formed of the polymeric film or sheet and an additional layer selected from the group consisting of glass, other polymeric interlayer sheets, polymeric film layers, and metal films or sheets. Examples of articles include safety windows and solar cells.

Abstract:

A polymeric film or sheet comprising an acid copolymer composition comprising acid copolymer of an alpha olefin and about 1 to about 30 wt % of alpha,beta-ethylenically unsaturated carboxylic acid having 3 to 8 carbons, based on the total weight of the acid copolymer composition, wherein the acid copolymer has a Melt Index of about 75 to about 600 g/10 min. The acid copolymer composition preferably comprises an additive selected from the group consisting of silane coupling agent, organic peroxide, and combinations thereof. In addition, an article comprising an interlayer formed of the polymeric film or sheet and an additional layer selected from the group consisting of glass, other polymeric interlayer sheets, polymeric film layers, and metal films or sheets. Examples of articles include safety windows and solar cells.
