    摘要： A method of preparing polymer, the method comprising polymerising one or more ethylenically unsaturated monomers of formula (I) where U is selected from H, C1-C4 alkyl or halogen; V is halogen or of the form O-G where G is selected from —C(O)R1 and —R1, or V is of the form NGGa where G is as defined above and Ga is selected from H and R1, G and Ga form together with N a heterocyclic ring, or V is of the form CH2Gb where Gb is selected from H, R1, OH, OR1, NR12, PR12, P(O)R12, P(OR1)2, SR1, SOR1, and SO2R1; and where the or each R1 is independently selected from optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted arylalkyl, optionally substituted heteroarylalkyl, optionally substituted alkylaryl, optionally substituted alkylheteroaryl, and an optionally substituted polymer chain, under the control of a RAFT agent of formula (II) or (III), where Y is a Lewis base moiety and Y* is an n-valent Lewis base moiety; X is O or NR1, R1 is as defined above or forms together with Y or Y* and N a heterocyclic ring; m is an integer ≧1; n is an integer ≧2; and where R* is a m-valent radical leaving group that affords R*. which initiates free radical polymerisation of the one or more ethylenically unsaturated monomers of formula (I), and R is a free radical leaving group that affords R. which initiates free radical polymerisation of the one or more ethylenically unsaturated monomers of formula (I).

    摘要： The invention provides in one aspect a process for preparing a microgel by RAFT polymerizing in the presence of a RAFT chain transfer agent, one or more solvophobic monomers and one or more solvophilic monomers to form one or more block copolymers comprising one or more solvophobic blocks and one or more solvophilic blocks wherein the solvophobic block is insoluble in a dispersing medium and the solvophilic block is soluble in the dispersing medium. The block copolymer is dispersed in the dispersing medium to form micelles, which is then stabilized to form the microgel. The dispersing medium can be aqueous or lipophilic. The method of the present invention also permits one to encapsulate a wide variety of materials, such as pigments, dye molecules, and aluminum flakes used in metallized paints.

    摘要： This invention relates to a process for controlling the architecture of copolymers of at least two unsaturated monomers, made by free-radical polymerization in the presence of a cobalt-containing chain transfer agent, including the control of molecular weight, degree of branching and vinyl end group termination, by varying at least one of the variables of molar ratio of monomers, their relative chain transfer constants, polymerization temperature and degree of conversion and amount of cobalt chain transfer agent; and polymers made thereby.
