Abstract
This invention relates to a process for making phenolic fatty acid compounds having a reduced phenolic ester content. The invention also relates to method for chemically bonding a phenolic resin with a non-phenolic polymer (e.g., a synthetic fabric). The method comprises contacting a phenolic fatty acid compound with a non-phenolic polymer to introduce a hydroxy phenyl functional group into the non-phenolic polymer; and reacting the hydroxy phenyl functional group contained in the non-phenolic polymer with a phenolic resin or a phenolic crosslinker composition capable of forming a phenolic resin, to chemically bond the phenolic resin with the non-phenolic polymer. The invention is particularly useful for making a synthetic fabric-reinforced article, such as synthetic fabric-reinforced rubber article, circuit board substrate, or fiberglass.
