A hydrophilic low acid content resin includes a polymerization product of a mixture including at least one (meth)acrylate and at least one (meth)acrylic acid; wherein the resin is water soluble; and the resin exhibits an acid value from 0 to about 120.

Hydrophilic, low acid content polymers as stabilizers for water-based emulsions

A process of preparing a water-based emulsion includes adding a first monomer feed to a reaction vessel in the presence of a first initiator and water to form an acid-functional polymer; neutralizing the acid-functional polymer to form a particulate polymer; and adding a second monomer feed to the reaction vessel in the presence of a second initiator to form an agglomerated polymer; where the process is a one-pot process. The first monomer feed includes a unbranched (meth)acrylate monomer, a (meth)acrylic acid monomer, a branched (meth)acrylate, and a styrenic monomer; the second monomer feed includes a hydrophobic monomer; the water-based emulsion includes the agglomerated polymer; the agglomerated polymer includes the particulate polymer; and the agglomerated polymer having an aggregated drupelet morphology. The agglomerated polymers may be used in high opacity emulsions.

Water-based polymer emulsions for opaque films and coatings applications

A thermosettable coating composition comprises a reaction product of a polyurethane polymer having at least one pendant carbamate functional group and a crosslinker reactive with the at least one pendant carbamate functional group. The polyurethane polymer is a polymerization reaction product of at least one diol having a primary carbamate functional group and at least one polyisocyanate. A method of forming a thermosettable coating composition includes polymerizing a mixture to form the polyurethane polymer, and combining the polyurethane polymer and a crosslinker reactive with the at least one pendant carbamate functional group to form the thermosettable coating composition. A coated article formed from the thermosettable coating composition is also disclosed.
