Document Type and Number:
Japanese Patent JP2006517248
Kind Code:
A
Abstract:
The present invention relates to the modification of copolymers, in particular of grafted copolymers into comb copolymers. The modification comprises the steps (i) of controlled radical polymerization of a polymer or copolymer bearing a epoxide group at one end resulting from the initiation step, and (ii) a heating step of the polymer prepared under (i) and a copolymer bearing a functional group either in the backbone or attached to a side chain, which is able to react with the epxide group. The result is a comb copolymer with well controlled chain length of the grafted side arms expressed for example by a low polydispersity.
