Abstract

N,N'-Dimethyl acrylamide and n-butyl acrylate have been grafted from crosslinked poly( divinylbenzene) core microspheres by both reversible addition-fragmentation chain transfer (RAFT) polymerization and conventional free radical polymerization. The microspheres were prepared by precipitation polymerization utilizing 55 and 80 wt. % divinylbenzene (DVB), respectively. The RAFT agent cumyl dithiobenzoate (CDB) was utilized and grafting was performed in toluene at 80 degrees C with 2,2'-azoisobutyronitrile (AIBN) as thermal initiator. Particle weights increased up to 6% for poly(n-butyl acrylate) and up to 15% for poly(N,N'-dimethyl acrylamide). Grafting from poly(DVB-55) microspheres results in a higher particle weight increase than grafting from poly(DVB-80) microspheres while using the same RAFT agent concentrations. The particle weight increase is approximately higher by a factor of two. The grafted microspheres were characterized by attenuated total reflection (ATR) IR spectroscopy and scanning electron microscopy.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
