A COMONOMER, AND A POLYMER STABILIZED WITH IT DURING POLYMERIZATION

摘要

The invention concerns an E-vitamin derivative or a compound analogous with it, having formula (I), where X is an oxygen or sulfur atom, p is an integer 0 or 1, and R3 - R11 are identical or different groups selected from hydrogen, C1-6alkyl or .alpha.-alkene having formula (II), where n, m and o are intege rs 0 - 4 independent of each other and R1 and R2 are identical or different groups selected from hydrogen or C1-6alkyl or C1-6alkene, which may be substituted with an aromatic ring, or R7 and R8 are together an oxygen atom and/or R4 and R5 and/or R10 and R11 form together with the carbon atoms to which they are bonded a benzene ring, which may be substituted with groups selected from hydrogen, C1-6alkyl or .alpha.-alkene. The invention also concerns the use of a derivative consistent with formula (I) as a stabilizin g comonomer, and a stabilized copolymer and a method for the production of a stabilized copolymer.
