HYDROXYLAMINE ESTERS AS POLYMERIZATION INITIATORS

摘要

The invention relates to novel cyclic and open-chain hydroxylamine esters an d polymerizable compositions comprising these hydroxylamine esters and an ethylenically unsaturated monomer or oligomer. The invention also relates to use as polymerization initiators and to the use of known hydroxylamine ester s selected from the group consisting of HALS compounds and the novel hydroxylamine esters for the controlled degradation of polypropylene and for achieving a controlled increase in the molecular weight of polyethylene.
