nitroxyl derivatives with glycidyl or alkylcarbonyl groups as initiators for radical polymerisationen

摘要

Glycidyl and alkylcarbonyl functional nitroxide radical polymerization initiator compounds of formula (Ia) or (Ib),where R1, R2 and A are as defined within,R3 is a radical of formula (II) whereX is phenylene, naphthylene or biphenylene, which are unsubstituted or substituted by NO2, halogen, amino, hydroxy, cyano, carboxy, C1-C4alkoxy, C1-C4alkylthio, C1-C4alkylamino or di(C1-C4alkyl)amino;the R12 are independently of each other H or CH3;D is a group a group C(O)-R13 or a group C(O)-R9-C(O)-R13;R13 is C1-C18alkyl andm is a number from 1 to 4, provide polymeric resin products having low polydispersity, polymerization processes that proceed with good monomer to polymer conversion efficiencies and polymers that contain a glycidyl or alkylcarbonyl group.
