Abstract: A carbonless copying color developer comprising a thermoplastic chelated metal modified phenolic resin formed from the in situ reaction of formaldehyde with a mixture of a para-substituted phenol, salicyclic acid, and a metal oxide. The reaction is conducted under hydrous conditions and at atmospheric pressure, with substantially no unreacted metal oxide residue.

Abstract: A tackifier system which includes the reaction product of oxirane bearing materials with alkyl phenol novolacs for elastomers of alpha-olefin polymers which are sulfur curable.The invention is directed to reaction products of alkyl phenol novolacs with oxirane bearing materials. The reaction products of alkyl phenol novolacs with oxirane bearing materials have been found to be excellent tackifiers for various types of elastomers.Further, the invention is directed to elastomer compositions containing reaction products of alkyl phenol novolacs with oxirane bearing materials. Elastomer compositions containing the reaction products of alkyl phenol novolac resins with oxirane bearing materials exhibit excellent tack properties.Tackifiers are employed in elastomeric compositions to produce wider practical ranges of elastomer properties, such as stiffness and tack. Tackifiers are used to improve adhesion, and sometimes cohesion without necessarily stiffening or softening the elastomer composition.

Abstract: Superior polychloroprene adehsives are prepared by incorporating the reaction product of an alkali catalyzed alkyl phenol-formaldehyde resin and zinc resinate. Preferably an arylphenol and/or bisphenol A is also incorporated. Also preferably rosin is included in the composition. Other zinc compounds, e.g. zinc oxide, zinc borate, zinc phosphate, zinc carbonate, and zinc salicylate can be used in place of zinc resinate.
