| 摘要 |
This invention relates to a process for the synthesis of addition polymers containing branches upon branches and having a polymerizable olefin end group by a convenient one-pot copolymerization of selected vinyl monomers with chain polymerization initiators and a method to provide olefin end groups by chain transfer or termination agents; and polymers produced thereby. The process comprises contacting: i) one or more vinylic monomers having the formula CH2=CYZ, and ii) a chain transfer agent of formula CH2=CQ-CH2-X wherein: Y is selected from the group consisting of OR, O2CR, halogen, CO2H, COR, CO2R, CN, CONH2, CONHR, CONR2 and R'; Z is selected from H, CH3 or CH2OH; R is selected a large number of groups. See enclosed definitions.
