HTEMPO-functionalized central cores were formed with divinylbenzene in ’’core first’’ method,and the four or five arms star polymers were built via controlled/living free radical photopolymerization.The four arms star polymers were also prepared with controlled/living free radical photopolymerization in ’’arm first’’ method.The resulting polymers had been confirmed by GPC and 1 H NMR.It showed that the star polymers had low polydispersities and molecular weight(M n) with the 85,000-560,000 g/mol range.
