Abstract:
A product obtained by transforming groups of the formula (G-I) being present in a block oligomer having a polydispersity {overscore (M)}w/{overscore (M)}n of 1 to 1.7 and corresponding to the formula (I) to groups of the formula (G-II); wherein R1 is a hydrocarbyl radical or â€”Oâ€”R1 is oxyl;said transformation is carried out by reaction of the block oligomer corresponding to the formula (I) with a hydroperoxide in a hydrocarbon solvent in the presence of a peroxide decomposing catalyst;n is a number from 2 to 14; the radicals R2 are independently of one another C2-C12alkylene, C4-C12alkenylene, C5-C7cycloalkylene, C5-C7cycloalkylenedi(C1-C4alkylene), C1-C4alkylenedi-(C5-C7cycloalkylene), phenylenedi(C1-C4alkylene) or C4-C12alkylene interrupted by 1,4-piperazinediyl, â€”Oâ€” or >Nâ€”X1 with X1 being C1-C12acyl or (C1-C12alkoxy)carbonyl or having one of the definitions of R4 given below; or R2 is a group of the formula (a), (b) or (c); with m being 2 or 3, X2 being C12-C18alkyl, C5-C12cycloalkyl which is unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl; phenyl which is unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl or C1-C4alkoxy; C7-C9phenylalkyl which is unsubstituted or substituted on the phenyl by 1, 2 or 3 C1-C4alkyl; and the radicals X3 being independently of one another C2-C12alkylene; the radicals A are independently of one another â€”OR3, â€”N(R4)(R5) or a group of the formula (11); R3, R4 and R5, which are identical or different, are C1-C18alkyl, C5-C12cycloalkyl which is unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl; C3-C18alkenyl, phenyl which is unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl or C1-C4alkoxy; C7-C9phenylalkyl which is unsubstituted or substituted on the phenyl by 1, 2 or 3 C1-C4alkyl; tetrahydrofurfuryl or C2-C4alkyl which is substituted in the 2, 3 or 4 position by â€”OH, C1-C8alkoxy, di(C1-C4alkyl)amino or a group of the formula (III); with Y being â€”Oâ€”, â€”CH2â€”, â€”CH2CH2â€” or >Nâ€”CH3; and R3 is additionally hydrogen or â€”N(R4)(R5) is additionally a group of the formula (III); X is â€”Oâ€” or >Nâ€”R6; R6 is C1-C18alkyl, C3-C18alkenyl, C5-C12cycloalkyl which is unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl; C7-C9phenylalkyl which is unsubstituted or substituted on the phenyl by 1, 2 or 3 C1-C4alkyl; tetrahydrofurfuryl, a group of the formula (G-I), or C2-C4alkyl which is substituted in the 2, 3 or 4 position by â€”OH, C1-C8alkoxy, di(C1-C4alkyl)amino or a group of the formula (III); the radicals R have independently of one another one of the meanings given for R6; and the radicals B and B* have independently of one another one of the meanings given for A; with the proviso that in the individual recurrent units of the formula (I), each of the radicals B, R and R2 has the same or a different meaning.
