    摘要： An amine ether of formula A wherein a is 1 or 2; and when a is 1, E is E′; when a is 2, E is L; E′ is C1-C36 alkyl; C3-C18 alkenyl; C2-C18 alkinyl; C5-C18 cycloalkyl; C5-C18 cycloalkenyl; a radical of a saturated or unsaturated aliphatic bicyclic or tricyclic hydrocarbon of 7 to 12 carbon atoms; C2-C7alkyl or C3-C7alkenyl substituted by halogen; C7-C15 aralkyl or C7-C15 aralkyl substituted by C1-C4 alkyl or phenyl; or E′ is a radical of formula (VII) as explained in claim 1; T′ is tertiary C4-C18alkyl or phenyl, each of which are unsubstituted or substituted by halogen, OH, COOR21 or C(O)—R22; or T′ is C5-C12cycloalkyl; C5-C12cycloalkyl which is interrupted by at least one O or —NR18—; a polycyclic alkyl radical having 7-18 carbon atoms, or the same radical which is interrupted by at least one O or —NR18—; or T′ is —C(G1)(G2)-T″; or C1-C18alkyl or C5-C12cycloalkyl substituted by T″ is hydrogen, halogen, NO2, cyano, or is a monovalent organic radical comprising 1-50 carbon atoms; or T″ and T′ together form a divalent organic linking group completing, together with the hindered amine nitrogen atom and the quaternary carbon atom substituted by G1 and G2, an optionally substituted five- or six-membered ring structure; and all other residues are as defined in claim 1, are obtained in good yield from the corresponding N-oxyl hindered amine precursor by reaction with a hydrocarbon E1-H or H-L-H in the presence of an organic hydroperoxide and a catalytic amount of copper or a copper compound. The products of present process find utility as polymerization regulators and/or light stabilizers for organic material.

    摘要： Composition comprising (a) catalytic amounts of a one-component catalyst for metathesis polymerization and (b) at least one polymer with strained cycloalkenylene radicals bonded in the polymer backbone, alone or as a mixture with strained cycloolefins. The composition can be polymerized thermally or photochemically by metathesis polymerization and is suitable for the production of shaped articles, coatings and relief images. The catalyst is selected from Ruthenium and Osmium compounds.
