Abstract
Methods of forming acrylate polymers using emulsion polymerization techniques are described. The resulting acrylate polymers exhibit characteristics enabling their use in adhesives and replacing acrylic polymers formed by solvent-based polymerization methods. Various polymers and adhesives utilizing such polymers are also described.
Claims29
An emulsion-based method of forming acrylate polymers, the method comprising:
- preparing a monomer phase including (i) one or more acrylate monomers, (ii) a controlled architecture acrylate oligomer, and (iii) one or more acrylate co-stabilizers;
- emulsifying the monomer phase using one or more copolymerizable surfactants to form a mini-emulsion;
- preparing a seed latex from the mini-emulsion.
