Abstract
Methods of making low molecular weight methylene acceptors are provided. The methylene acceptors are prepared by reacting a polyhydric phenol with an aromatic olefinic compound in the presence of an acid catalyst, and then further reacting the products of the first reaction with an N-methylol lactam derivative. Derivatives made by the above method, as well as rubber compositions using these derivatives are also provided.
