The analysis of products was carried out by SEC with a MALLS detector. The influence of the feed policy of divinylbenzene on the time evolution of the copolymer molecular weights and <jats:italic>z<\/jats:italic>\u2010average mean square radius of gyration was assessed. A detailed kinetic model, in the absence of intramolecular reactions but taking into account the presence of the two isomers m\u2010 and p\u2010 in the commercial divinylbenzene and the different reactivities of the various radicals and double bonds was developed; most parameters have been collected from previous kinetic studies, and only two have been regressed using our measured molecular weights. These results can be used to improve the production of branched\/crosslinked polymers with controlled molecular architecture.<\/jats:p>","DOI":"10.1002\/masy.200751315","type":"journal-article","created":{"date-parts":[[2007,12,11]],"date-time":"2007-12-11T11:47:03Z","timestamp":1197373623000},"page":"124-134","source":"Crossref","is-referenced-by-count":15,"title":["Time Programmed Feed of Semi\u2010Batch Reactors with Non\u2010Linear Radical Copolymerizations: An Experimental Study of the System Styrene\u2009+\u2009Divinylbenzene Using SEC\/MALLS"],"prefix":"10.1002","volume":"259","author":[{"given":"Miguel A.
