Abstract
AbstractReactive intramolecularly crosslinked macromolecules (RICM) (reactive microgels) have been synthesized by emulsion copolymerization. Besides 1,4‐divinylbenzene (1,4‐DVB), self‐emulsifying unsaturated polyesters (EUP) were used. In copolymerization of EUP and comonomers the diffusion rate of the latter influences the copolymerization rate of the growing species, if the initiator concentration is high and the water solubility of the difunctional comonomer is low. The compact structure of RICM is indicated by low slopes of log [\eta]/logw. Values of [\eta] of RICM are low and their molar masses high. [\eta] depends on the structure of RICM, e.g. pendent chains and crosslink density. Structures with pendent EUP chains could be confirmed by hydrolytic degradation. RICM may be stabilized electrostatically or sterically. Network chains of RICM from 1,4‐DVB are immobile.
