Block polymer, useful for optical elements and data storage contains a block comprising at least 3 repeating units not containing photoisomerizable groups and a block containing STQP groups

摘要

A block polymer contains at least one block comprising at least 3 repeating units not containing photoisomerizable groups and at least one block containing STQP groups. A polymer (I) having different blocks, contains at least one block (A) comprising at least 3 repeating units of formula (C1) and at least one block (B) having repeating units of formula (C2). [Image] R100, R102H or methyl; R701H or 1-8C alkyl without photoisomerizable groups, preferably methyl, ethyl, propyl, n-butyl, preferably methyl; R103[STQP]; P : A and/or M. Independent claims are included for: (i) a process for the production of the block polymer (I) by controlled polymerization to form the individual blocks of the copolymer having a defined structure and mol. wt. with anionic polymerization of monomers, also partially protected OH-functionalized monomers based on acrylate and methacrylate as well as controlled radical polymerization of functionalized monomers; (ii) optionally elements and storage, preferably volume storage (II) comprising at least one block polymer (I) having a through radiated thickness of 0.1 mm; and (iii) a process for the production of optical elements and storage (II) by injection molding.
