Beschreibung
Zusammenfassung:	This invention relates to semi-batch type copolymerization processes. More specifically, the processes of the present invention are directed to the production of compositionally uniform copolymers, including the production of such copolymers from dissimilar monomers, e.g., from monomers with significantly different reactivity ratios. Cette invention porte sur des procédés de copolymérisation de type semi-discontinu. Plus spécifiquement, les procédés de la présente invention se rapportent à la production de copolymères de composition uniforme, comprenant la production de tels copolymères à partir de monomères dissemblables, par exemple, à partir de monomères ayant des rapports de réactivité significativement différents.
