    摘要： A process for forming a microgel which comprises a crosslinked core and a multiplicity of linear polymeric arms attached to the core, wherein the process comprises (a) first forming a halogen atom terminated prepolymer with a weight average molecular weight from 1,000 to 25,000 by polymerizing monoethylenically unsaturated monomers in the presence of an organic sulfonyl halide, an organic complexing agent and a transition metal (i.e., Cu, Ru, Ni, Re, Pd, Fe, or Rh); and (b) subsequently polymerizing the prepolymer with a mixture of monoethylenically unsaturated monomers and 0.5 to 60 mole percent, based on the total moles of monomer and prepolymer, of multi-olefinic polymerizable monomers to form a microgel with a weight average molecular weight of 10,000 to 100,000,000 and crosslinked core.

    摘要： A process for preparing microgel(s) that uses a wide range of activatable prepolymers; in the process, a polymer composition of crosslinked component A and soluble components B and C is formed from mono-olefinic and multi-olefinic monomers in the presence of catalyst and initiator; the process comprises: I) introducing mono-olefinic monomer, catalyst, and initiator into a reactor in the absence of multi-olefinic monomer and producing an activatable prepolymer, component B; II) contacting the product of I) with multi-olefinic monomer to produce components A and C, optionally in the presence of additional initiator; also optionally in the presence of additional mono-olefinic monomer and initiator; the ratio of components A/(B+C) can be controlled by varying the mole ratio of Component B/multi-olefinic monomer from 0.05/1 up to 5/1, by decreasing the mole ratio to increase the ratio of A/(B+C), and increasing the mole ratio to decrease the ratio of A/(B+C).

    摘要： A process for preparing microgel(s) that uses a wide range of activatable prepolymers. In the process, a polymer composition of crosslinked component A and soluble components B and C is formed from mono-olefinic and multi-olefinic monomers in the presence of catalyst and initiator. The process comprises: I) introducing mono-olefinic monomer, catalyst, and initiator into a reactor in the absence of multi-olefinic monomer and producing an activatable prepolymer, component B; II) contacting the product of I) with multi-olefinic monomer to produce components A and C, optionally in the presence of additional initiator; also optionally in the presence of additional mono-olefinic monomer and initiator. The ratio of components A/(B+C) can be controlled by varying the mole ratio of The Component B/multi-olefinic monomer from 0.05/1 up to 5/1, by decreasing the mole ratio to increase the ratio of A/(B+C), and increasing the mole ratio to decrease the ratio of A/(B+C).
