Abstract
A silane-modified phenolic resin is prepared by reacting a phenolic compound (e.g., resorcinol) with an aldehyde to produce a phenolic novolak resin. The phenolic novolak resin is further reacted with at least one silane compound to produce the silane-modified phenolic resin. The reaction is typically carried out in the presence of an acid or base catalyst. The resulting resin has a lower softening point and can be used as a methylene acceptor compound in a vulcanizable rubber composition.
