摘要： The present invention relates to a process of preparing block copolymers comprising of at least two types of homoblocks, selected from either PSSD, PSSB, TPES, PSS, TMPSS or PESK or selected from at least one of PSSD, PSSB, TPES, PSS, TMPSS or PESK and at least one of PPSU, PES or PSU, wherein each of the said homoblock has an identical or different molecular weight of at least 1000 and has at least 5 % of the overall weight and wherein the block copolymer has a molecular weight of at least 2000, the process steps comprising of preparing each of the aforesaid homoblocks by heating at least one aromatic diol/dihydroxy compound with at least one aromatic dihalo compound, one of which contains at least one sulfone group, in the presence of at least one alkali optionally in at least one solvent and further optionally in the presence of an azeotropic agent, reacting the aforesaid homoblocks together at a temperature between 1300C to 2500C optionally in at least a solvent, and further optionally followed by end-capping said block copolymer recovering the block copolymer and to the block copolymer prepared therefrom.
