    Abstract: Cationic 2,2,6,6-tetraalkylpiperidinyl alkoxyamines of, for example, formula (1a) and (1b) are useful as polymerization initiators/regulators in a controlled stable free radical polymerization process to produce intercalated and/or exfoliated nanoparticles from natural or synthetic clays. Compositions comprising improved nanocomposites produced by this process are useful as, for example, coatings, sealants, caulks, adhesives and plastic additives wherein Q1 is a direct bond or a —CH2— group T1, T2, T3 and T4 are independently methyl or ethyl with the proviso that at least one is ethyl; T7 and T8 are hydrogen or methyl; T5 and T6 are hydrogen or T5 and T6 together are a group ═O, ═NOH, ═NO-T9 or T5 is hydrogen and T6 is —O-T9 or —NR9-T9 T9 is hydrogen, R9 or —C(O)—R9; R9 is hydrogen, C1-C18alkyl, C3-C18alkenyl, C3-C18alkynyl, phenyl or C7-C9phenylalkyl unsubstituted or substituted by hydroxy, halogen or C1-C4alkoxy; K1 and K2 are hydrogen, C1-C18alkyl, C5-C12cycloalkyl, phenyl or C7-C9phenylalkyl and K3 is a group containing selected amine containing salts.
