Abstract
Addition polymers of ethylenically unsaturated monomers are provided comprising a 5-, 6- or 7-membered polymer unit formed from a copolymerizable, unsaturated, chain transfer agent containing a labile hydrogen and capable of forming by means of a hydrogen shift mechanism a free radical having 5, 6 or 7 atoms between and including the .alpha.-carbon of the ethylenically unsaturated group and the labile hydrogen.
