  The invention relates to novel cyclic and open-chain hydroxylamine esters and 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 esters 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.

  该发明涉及新型环状和开链羟胺酯以及包括这些羟胺酯和乙烯基不饱和单体或寡聚物的可聚合组合物。该发明还涉及用作聚合引发剂以及用于控制聚丙烯降解和实现聚乙烯分子量控制增加的已知羟胺酯，所述羟胺酯来自HALS化合物和新颖羟胺酯的组合。
