Anti-migratory additive for emulsified phenolic resin systems containing a proteinaceous colloid

A method for making an emulsified liquid phenolic resin system anti-migratory wherein such system contains spherules of phenolic resin dispersed in aqueous medium at least about 80 weight percent of the spherules ranging in maximum dimension from about 0.01 to 0.8 microns, and further contains:

• A. a quantity of solids ranging from about 5 to 45 parts by weight, comprising the phenolic resin and a water soluble dissolved protenaceous protective colloid in basic form, in the weight ratio in the range of 99:1 and 88:12;
• B. a quantity of organic liquid ranging from about 0 to 20 parts by weight, and
• C. a quantity of water ranging from 35 to 95 parts by weight;
• wherein the phenolic resin is characterized by:
• 1. having a water dilutability of from 15 percent to 2000 percent based on the resin solids,
• 2. having a formaldehyde to phenol combined mole ratio of from about 0.85 to 3.0, and
• 3. having a viscosity in methanol solution at 60 weight percent solids concentration of not greater than about 10,000 centipoises;
• which comprises admixing with such system an aqueous solution of a water soluble polyacrylate salt containing from about 0.04 to 20 parts by weight of the salt per 100 parts of solids of the combined liquid phenolic resin system and the aqueous solution, wherein the polyacrylate salt is characterized by:
• 1. having its cations selected from the group consisting of alkali metals and ammonium;
• 2. having a molecular weight of from about 100,000 to 700,000,
• 3. having a pH of from about 8 to 10 when in a 13 weight percent aqueous solution, and
• 4. containing at least about 100 units per molecule of the structure:
