Abstract
Methods for preparing low free resorcinol resins are disclosed. These methods generally comprise reacting a resin with an aromatic olefinic compound; suitable resins include one or more resins selected from the group consisting of a dihydric phenol, a polyhydric phenol, a dihydric phenolic novolak resin and a polyhydric phenolic novolak resin; the addition product of at least one of these resins and at least one compound selected from the group consisting of a monooxirane compound and a polyoxirane compound; and a phenol or alkyl or aralkyl substituted mono- or dihydric phenol modified form of these resins. The resins produced by this method are also disclosed, as are rubber compositions utilizing the resin produced by this method.
Claims23
A method for reducing the free phenolic monomer content in a compound comprising reacting an effective amount of an aromatic olefinic compound with the free phenolic monomer in said compound;
- wherein the compound is selected from the group consisting of:
- (a) one or more resins selected from the group consisting of a monohydric phenolic resin, a clihydric phenolic resin and a polyhydric phenolic resin;
- (b) the addition product of at least one compound selected from the group consisting of a dihydric phenol, a polyhydric phenol, a dihydric phenolic resin and a polyhydric phenolic resin, and at least one compound selected from the group consisting of a monooxirane compound and a polvoxirane compound;
- and
- (c) a monohydric phenolic resin, a dihydric phenolic resin or a polyhydric phenolic resin that comprises one or more substituents selected from the group consisting of an alkyl group and an aralkyl group;
- and
- wherein said aromatic olefinic compound is selected from the group consisting of vinyl naphthalene and aromatic olefinic compounds having the formula ##STR4## wherein (R) is selected from the group consisting of H, CH.sub.3 and halogen;
- and R.sub.1 is independently selected from the group consisting of H, OH, an alkyl group having from 1 to 6 carbons, a halogen and --CH=CH.sub.2.
A compound having less than 10% volatile free phenolic monomer, said compound comprising the additional product of said free phenolic monomer and an aromatic olefinic compound, wherein said compound is selected from the group consisting of:
- (a) one or more resins selected from the group consisting of a monohydric phenolic resin, a dihydric phenolic resin and a polyhydric phenolic resin;
- (b) the addition product of at least one compound selected from the group consisting of a dihyclric phenol, a polyhydric phenol, a dihydric phenolic resin and a polyhydric phenolic resin, and at least one compound selected from the group consisting of a monooxirane compound and a polyoxirane compound;
- and
- (c) a monohydric phenolic resin, a dihydric phenolic resin or a polyhydric phenolic resin that comprises one or more substitutients selected from the group consisting of an alkyl group and an aralkyl group;
- and
- wherein said aromatic olefinic compound is selected from the group consisting of vinyl naphthalene and an aromatic olefinic compound having the formula (3) ##STR5## wherein (R) is selected from the group consisting of H, CH.sub.3 and halogen;
- and R.sub.1 is independently selected from the group consisting of H, OH, an alkyl group having from 1 to 6 carbons, a halogen and --CH=CCH.sub.2.
