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.

First claim

We claim:

1 . A synthetic-fabric reinforced rubber composition, comprising:
a synthetic fabric containing a synthetic-fabric phase that has been (a) modified by a phenolic fatty acid compound to contain a hydroxy phenyl functional group, and (b) coated with a phenolic resin, wherein the synthetic-fabric phase and the coated phenolic resin are chemically bonded through the hydroxy phenyl functional group; and a rubber composition.

2 . The synthetic-fabric reinforced rubber composition of claim 1 , wherein the synthetic-fabric phase has been modified to contain a hydroxy phenyl functional group via a reaction of a functional group in the synthetic-fabric phase with a carboxylic acid group in the phenolic fatty acid compound.

3 . The synthetic-fabric reinforced rubber composition of claim 1 , wherein synthetic fabric is a material selected from the group consisting of nylon, rayon, polyester, aramid, polysulfone, and combinations thereof.

4 . The synthetic-fabric reinforced rubber composition of claim 1 , wherein the phenolic resin is a monohydric, dihydric, or polyhydric phenol-aldehyde resin, wherein monohydric, dihydric, or polyhydric phenol of the phenol-aldehyde resin is unsubstituted or substituted with one or more linear, branched, or cyclic C 1 -C 30 alkyl.

5 . The synthetic-fabric reinforced rubber composition of claim 1 , wherein the phenolic resin further comprises an elastomeric latex.

6 . The synthetic-fabric reinforced rubber composition of claim 5 , wherein the phenolic resin is a resorcinol-formaldehyde-latex solution.

7 . The synthetic-fabric reinforced rubber composition of claim 1 , wherein the phenolic fatty acid compound comprises hydroxyphenyl stearic acid, hydroxyphenyl oleic acid, hydroxyphenyl linoleic acid, and combinations thereof.

8 . The synthetic-fabric reinforced rubber composition of claim 1 , wherein the phenolic fatty acid compound comprises [9,10]-(p-hydroxyphenyl)-octadecanoic acid.

9 . The synthetic-fabric reinforced rubber composition of claim 1 , wherein the synthetic fabric-reinforced rubber composition is a component of a composition selected from the group consisting of a tire, belt, hose, printing roll, rubber shoe heel, rubber shoe sole, rubber wringer, automobile floor mat, mud flap for trucks, ball mill liner, and weather strip.

10 . A synthetic-fabric reinforced article, comprising:
a synthetic fabric containing a synthetic-fabric phase that has been modified by a phenolic fatty acid compound to contain a hydroxy phenyl functional group, and an article comprising a phenolic resin, wherein the synthetic-fabric phase and the article are chemically bonded through the hydroxy phenyl functional group.

11 . The synthetic-fabric reinforced article of claim 10 , wherein the synthetic-fabric phase has been modified to contain a hydroxy phenyl functional group via a reaction of a functional group in the synthetic-fabric phase with a carboxylic acid group in the phenolic fatty acid compound.

12 . The synthetic-fabric reinforced article of claim 10 , wherein synthetic fabric is a material selected from the group consisting of nylon, rayon, polyester, aramid, polysulfone, and combinations thereof.

13 . The synthetic-fabric reinforced article of claim 10 , wherein the phenolic resin is a monohydric, dihydric, or polyhydric phenol-aldehyde resin, wherein monohydric, dihydric, or polyhydric phenol of the phenol-aldehyde resin is unsubstituted or substituted with one or more linear, branched, or cyclic C 1 -C 30 alkyl.

14 . The synthetic-fabric reinforced article of claim 10 , wherein the phenolic resin further comprises an elastomeric latex.

15 . The synthetic-fabric reinforced article of claim 14 , wherein the phenolic resin is a resorcinol-formaldehyde-latex solution.

16 . The synthetic-fabric reinforced article of claim 10 , wherein the phenolic fatty acid compound comprises hydroxyphenyl stearic acid, hydroxyphenyl oleic acid, hydroxyphenyl linoleic acid, and combinations thereof.

17 . The synthetic-fabric reinforced article of claim 10 , wherein the phenolic fatty acid compound comprises [9,10]-(p-hydroxyphenyl)-octadecanoic acid.

18 . The synthetic fabric-reinforced article of claim 10 , wherein the article is a rubber article.

19 . The synthetic fabric-reinforced article of claim 10 , wherein the article is a circuit board substrate.

20 . The synthetic fabric-reinforced article of claim 10 , wherein the article is a fiberglass.
