Abstract
Aqueous polymeric emulsions are formed by the inter-polymerization reaction product of at least one monomer having a reactive CH.sub.2 =C< group (e.g., vinyl acetate and alkyl acrylates) and an alkyd resin which is modified by the incorporation therein of certain ethylenically unsaturated monomers.
Claims4
An aqueous emulsion vehicle comprising the interpolymerization reaction product of
- a. from about 60 to about 90% by weight based on the total monomer/resin weight of at least one monomer having the polymerization-reactive CH.sub.2 =C<
- grouping selected from the group consisting of
- 1. Vinyl acetate and
- 2. alkyl acetate and methacrylate monomers wherein the alkyl radical contains from 1 to 10 carbon atoms;
- and
- b. from about 10 to about 40% by weight based on the total monomer/resin weight of an acrylic modified alkyd resin produced by the condensation reaction of at least one of each of the following:
- 1. an esterifiable polyhydric alcohol,
- 2. saturated, mono-unsaturated, or poly-unsaturated fatty acid or fatty acid oil;
- 3. A polycarboxylic acid or anhydride thereof;
- and
- 4. a monomer selected from the class of compounds having the formula:
- ##STR2## wherein R is --H or --CH.sub.3 and R.sub.1 is --H or a branched or unbranched lower alkyl group of from 1 to 10 carbon atoms.

An aqueous emulsion vehicle comprising the interpolymerization reaction product of
- a. from about 70 to about 85% by weight based on the total monomer/resin weight of at least one monomer having the polymerization-reactive CH.sub.2 =C<
- grouping selected from the group consisting of
- 1. vinyl acetate and
- 2. alkyl acrylate and methacrylate monomers wherein the alkyl radical contains from 1 to 6 carbon atoms;
- and
- b. from about 15 to about 30% by weight based on the total monomer/resin weight of an acrylic modified alkyd resin produced by the condensation reaction of at least one of each of the following:
- 1. an esterifiable polyhydric alcohol,
- 2. a saturated, mono-unsaturated, or poly-unsaturated fatty acid or fatty acid oil;
- 3. a polycarboxylic acid or anhydride thereof;
- and
- 4. a monomer selected from the class of compounds having the formula:
- ##STR3## wherein R is --H or --CH.sub.3 and R.sub.1 is --H or a branched or unbranched lower alkyl group of from 1 to 10 carbon atoms.
