NO-COMPOUNDS FOR PSEUDO-LIVING RADICAL POLYMERIZATION

摘要

The invention pertains to a process for pseudo-living radical polymerization's in which use is made of specific NO-compounds, called initers, according to formula (I) or (II) wherein: R represents a group which has at least one carbon atom and is such that the free radical R. is capable of initiating the free radical polymerization of unsaturated monomers; at most five of the groups represented by X1-X6 are the same or different straight-chain or branched substituted or unsubstituted alkyl groups, wherein two or more of the groups may be linked to form cyclic structures, or wherein -CX1X2X3 and/or -CX4X5X6 are phenyl, the complementary groups X1-X6 are functional groups, and, X7 and X8 are independently selected from alkyl, aryl, alkaryl, and aralkyl, while X7 is optionally linked with X8 to form bridged structures. The invention further relates to certain NO compounds, (block) (co)polymers, and to a recycling process for such polymers.
