A method of controlled radical polymerization of N-acryloylmorpholine of high mol.wt. and low polydispersity with high monomer conversion and reaction time 8 hours or less by controlling the flux of radical initiators

摘要

A method of controlled radical polymerization, giving polymers with mol.wt. above 100000 g/mole with a polydispersity index below 1.2 for mol.wts. below 200000 and below 1.4 for mol.wts. above 200000, monomer conversion above 75% and polymerization time below 8 hours, using a organosulfur reversible chain transfer agent in which the flux of radical initiators in the polymerization medium is controlled An Independent claim is included for a hydrosoluble polymer of mol.wt. 250000 g/mole and polydispersity below 1.4 obtained by the method.
