Incorporation of boron complex into resin
Complexes, compositions, articles of manufacture, and method for making the same are provided herein. In one embodiment, a borate-polyol complex may be prepared by reacting a boron-containing compound and a polyol to form a reaction mixture and then neutralizing the reaction mixture to form a neutralized borate-polyol complex. The neutralized borate-polyol complex may then be used in combination with polymeric resins to form adhesive products, among other material products, which products can be in manufacturing articles.
1. An adhesive composition, consisting of:
a neutralized borate-polyol complex, the polyol of the neutralized borate-polyol complex selected from the group consisting of a diol, a triol, a polyol having 4 hydroxyl groups, and combinations thereof;
a phenol-formaldehyde or resorcinol-formaldehyde resin;
optionally, one or more materials selected from the group consisting of an inorganic filler material, an organic filler material, an alkali hydroxide material, and combinations thereof; and
water.
2. The adhesive composition of claim 1 , wherein the neutralized borate-polyol complex comprises a borate-polyol complex neutralized with a hydroxide.
3. The adhesive composition of claim 2 , wherein the polyol of the neutralized borate-polyol complex is selected from the group consisting of glycerol, ethylene glycol, propylene glycol, and combinations thereof.
4. The adhesive composition of claim 1 , wherein the borate of the neutralized borate-polyol complex is a boron material derived from the group consisting of boric acid, sodium borate, sodium metaborate, and combinations thereof.
5. The adhesive composition of claim 1 , wherein the neutralized borate-polyol complex is formed by a process comprising:
reacting glycerol and boric acid to form a complex, and

optionally from about 1 wt. % to about 30 wt. % of the one or more materials; and
water.
8. The adhesive composition of claim 7 , wherein the one or more materials comprises from about 0.01 wt. % to about 10 wt. % of an alkali hydroxide material.
9. The adhesive composition of claim 7 , wherein the one or more materials comprises:
from about 0.01 to about 15 wt. % of an inorganic filler; and
from 0 to about 16 wt. % of an organic filler.
10. The adhesive composition of claim 1 , wherein the polyol of the neutralized borate-polyol complex is selected from the group consisting of a diol, a triol, and combinations thereof.
11. An article of manufacture, comprising:
an adhesive composition consisting of:
