  • Patent number: 8809428
    Abstract: The present disclosure relates to golf balls having components including intermediate layers and outer cover layers prepared from blends of polyamides mixed with one or more functional polymer modifiers. The functional polymer modifier incorporates a copolymer or a terpolymer having a glycidyl group, hydroxyl group, maleic anhydride group or carboxylic group, or a mixture of these. When used in golf ball covers or mantles, these materials exhibit improved impact durability when compared to analogous balls but having ionomeric- or polyurethane-based layers of similar hardness.

  • Publication number: 20130338313
    Abstract: The invention is based on the discovery that a remarkable improvement in the performance of maleimide thermosets can be achieved by incorporating amide-extended maleimides into an adhesive formulation. Amide-extended maleimides described herein can be used to toughen bismaleimide thermosetting materials without sacrificing any thermal stability. Amide-extended maleimides are readily prepared by reacting a bismaleimide with an appropriate amine via the well-known Michael addition reaction. Acylation of the resulting secondary amines provides the amide-extended maleimide. The acylating agent can also be used to introduce polymerizable functional groups into the backbones of these thermoset monomers. Amide-extended acrylate and methacrylate monomers can also be prepared.
