A method of making the polyurethane foam article comprises the steps of reacting the first polyether polyol and methylene diphenyl diisocyanate to form the isocyanate prepolymer and reacting the isocyanate prepolymer with the isocyanate-reactive composition in the presence of the blowing agent to form the polyurethane foam article.

Processes for producing polymer microcapsules using vicinal functional oligomers are also described. The vicinal functional oligomers can be made by polymerizing an acrylate monomer, a styrene monomer, or both in the presence of a chain transfer agent. The vicinal functional oligomers can be reacted with epichlorohydrin to form vicinal epoxies. The vicinal epoxies can be reacted with polyamines to form epoxy polymer microspheres. The vicinal epoxies can be reacted with carbon dioxide in the presence of a catalyst to form vicinal cyclic carbonates. The vicinal cyclic carbonates can be reacted with polyamines to form isocyanate-free polymer microspheres. Polymer microspheres made by the processes are also described.
