ABSTRACT:
A modified resorcinol resin is prepared by reacting a phenolic compound (e.g., resorcinol) with an olefinically unsaturated compound (e.g., styrene) and two types of aldehyde: a formaldehyde and an alkyl aldehyde (e.g., butyraldehyde). The reaction is typically carried out in the presence of an acid catalyst. The resulting resin has a lower softening point and can be used as a methylene acceptor compound in a vulcanizable rubber composition.
