Abstract (en)

[origin: WO2007017614A2] A method for preparing a polymeric material including a multiblock copolymer with n blocks, where n is an integer no lower than 2, which method comprises at least one cycle of steps including (a) a step of synthesising a block by performing controlled free-radical polymerisation of one or more free-radical polymerisable monomers, and (b) a step of polymerising the monomers that were not converted during step (a) into a polymer having a number-average molecular weight lower than the number-average molecular weight of said block, wherein said cycle of steps is carried out at least for the (n-1) first blocks.
