US 2017/0282018 A1 · GOLF BALL WITH EXCELLENT INTERLAYER ADHESION BETWEEN ADJACENT DIFFERING LAYERS

Abstract

Golf ball and method for making it, comprising a first layer that comprises a first polymeric composition and is surrounded by and adjacent to a second layer comprising a second polymeric composition different than the first polymeric composition; with one of these layers further comprising at least one silane-containing adhesion promoter such as organosilanes and/or organosiloxanes throughout in an amount of from about 0.1 wt. % to about 5.0 wt. % of the entire layer. Neither layer is surface treated with at least one silane-containing adhesion promoter. The second layer may be the layer comprising the silane-containing adhesion promoter throughout, surrounded by a third layer that comprises a third polymeric composition that differs from the second polymeric composition and does not incorporate any silane-containing adhesion promoter. Strong interlayer bonding is therefore created both between the second layer and the first layer and between the second layer and the third layer.

Dependent claims

A golf ball comprising a first layer that consists of a thermoset rubber composition and is surrounded by and adjacent to a second layer consisting of an ionomer composition;

wherein only the thermoset rubber composition of the first layer comprises at least one silane-containing adhesion promoter throughout and in an amount of from about 0.1 wt. % to about 5.0 wt. %;
and
wherein the first layer and the second layer are not surface treated with any adhesion promoter at an interface between the first layer and second layer.

Dependencies are inferred from the claim text.
