A modified alkylresorcinol resin is prepared by reacting one or more alkylresorcinols with one or more aldehydes and optionally an olefinically unsaturated compound. The reaction may be carried out in the presence of a catalyst. The resulted modified alkylresorcinol resin can be used as a methylene acceptor that reacts with methylene donors in vulcanizable rubber compositions.
