Abstract: The invention herein disclosed provides a method for preparing fluoroelastomer film compositions including the steps of dissolving a fluoroelastomer gum selected from the group consisting of copolymers of vinylidene fluoride and hexafluoropropylene, and terpolymers of vinylidene fluoride, hexafluoropropylene and tetrafluoroethylene in a solvent, adding a vinyl copolymer to the gum solution, evaporating the solvent and leaving a film. A method is also provided for adhering fluoroelastomer film compositions, devoid of metallic oxides, to substrates which includes the steps of dissolving the fluoroelastomer gum in a solvent, adding a vinyl copolymer to the gum solution, coating the substrate with the fluoroelastomer gum-vinyl copolymer solution, evaporating the solvent and leaving a cured film firmly adhered to the substrate. The fluoroelastomer film compositions disclosed herein are also novel and can be used to coat a variety of substrates thereby providing other novel, useful articles.

So overlapped, the prepreg sheets (26,28) are simultaneously wound onto a mandrel (29) and cured to produce the aforesaid rod (20).

Abstract: A bowling ball according to one embodiment of the present invention has a hollow member (16), or a member of less specific gravity than the mass of the bowling ball, disposed therein with its centroid displaced from the geometric center of the ball. The lighter weight member in the ball permits the use of a dense polymerizable composition for the basic mass of the ball. The ball is molded without the usual shell so that it has a resilient striking surface for maximum impact and pin carry. In another embodiment, a member (46) of a higher specific gravity than that of the polymerizable mass is added generally on the same axis as the lighter weight member (42) to increase the eccentricity of the ball and give it even more driving power upon impact with the pins.
