US Patent:

RE291579, Mar 22, 1977

Filed:

Jul 10, 1972

Appl. No.:

5/270026

Inventors:

Kenneth C. Petersen - Scotia NY
Thomas M. Galkiewicz - Schenectady NY

Assignee:

Schenectady Chemicals, Inc. - Schenectady NY

International Classification:

C08L 9100

US Classification:

260 25

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.

US Classification:

260 51EP

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.

International Classification:

C08F 416

US Classification:

526 90

Abstract:

Styrene is homopolymerized or copolymerized with alpha methyl styrene, preferably in the presence of limonene, with or without t-butyl styrene, using zirconium tetrachloride as the catalyst. The light colored resins formed are useful as. [. drying. ]. . Iadd. dry. Iaddend. cleaning sizing agents and in hot melt adhesives.
