Patent number: 4876095Abstract: The present invention is a chewing gum base composition and a method for making same which includes an elastomer and a resin prepared in the absence of rosin esters and terpene components which includes an elastomer component raised to a compatibilization temperature for addition of a compatibilization component. The composition includes a high melting point compatibilization component added under low shear mixing conditions at a temperature sufficient to masticate the elastomer for forming a substantially homogeneous mass with the resin component. The compatibilization component is capable of effectuating dissociation of the elastomer under the conditions of temperature and mixing for forming the substantially homogeneous mass. Finally, a resin component is added also under low shear mixing conditions and mildly elevated temperatures until a substantially homogenous gum base mass is formed.Type: GrantFiled: May 20, 1986Date of Patent: October 24, 1989Assignee: Warner-Lambert CompanyInventor: Robert K.
