Patent number: 6232400Abstract: This invention provides a golf ball constituting or having a core layer, intermediate layer and/or cover layer consisting in whole or in part of a poly(trimethylene terephthalate) composition. The invention also provides methods for making such a ball. The compositions of the core layer, intermediate layer and/or cover layer may be foamed or unfoamed. The poly(trimethylene terephthalate) may comprise from about 1 to about 100 percent by weight of the core layer, intermediate layer and/or cover layer. In addition, the poly(trimethylene terephthalate) material may be blended with conventional materials employed to form golf ball cores, intermediate layers and/or covers.Type: GrantFiled: April 20, 1998Date of Patent: May 15, 2001Assignee: Acushnet CompanyInventors: Kevin Harris, Murali Rajagopalan

Patent number: 6203913Abstract: The present invention provides coating compositions including: (a) about 75 to about 99.9 weight percent of a crosslinkable film-forming system including one or more crosslinkable film-forming resins and one or more crosslinking materials which is capable of reacting with the film-forming resin to form a crosslinked film; and (b) one or more substantially saturated, predominantly hydrocarbon adhesion promoting agents having an average of more than one pendant or terminal polar group per molecule which are capable of reacting with the crosslinking material, the adhesion promoting agent(s) being present in an amount ranging from about 0.1 to about 25 weight percent on a basis of total resin solids of the coating composition. The coating compositions are useful for directly coating surfaces of thermoplastic and thermosetting plastic substrates, such as TPO and RIM, without the aid of flame or corona pretreatment, or the use of an adhesion promoter.Type: GrantFiled: December 16, 1998Date of Patent: March 20, 2001Assignee: PPG Industries Ohio, Inc.Inventors: Constantine A. Kondos, Edward E. McEntire, Masayuki Nakajima, Richard M. Nugent, Jr.
