Abstract
Reactive microgels are crosslinked macromolecules of globular shape. They may be prepared by polymerization of multifunctional monomers in emulsion or solution. Microgels are soluble in water or organic solvents. Their molecular mass is usually much higher than that of linear macromolecules of comparable diameters. By emulsion copolymerization (ECP) of unsaturated polyesters (UP) and styrene (S) microgels may serve as self-emulsifying component in ECP. Results on influence of molecular mass of UP and UP/S ratio on microgel yield, on the relation between structure and viscosity of microgel solution and on the ageing mechanism in dry state are reported.
