End-group analysis of polymers by electrospray ionization mass spectrometry: 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one initiated free-radical photopolymerization
Vana, P., Davis, T. P., & Barner-Kowollik, C. (2002) End-group analysis of polymers by electrospray ionization mass spectrometry: 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one initiated free-radical photopolymerization. Australian Journal of Chemistry, 55(5).
End-group analysis of poly(methyl acrylate) and poly(dicyclohexyl itaconate) initiated by 2-methyl-1[4-(methylthio) phenyl]-2-morpholinopropan-1-one (MMMP) has been performed by electrospray ionization mass spectrometry (ESI-MS). MMMP has been found to fragment into two radicals that are near-equally capable of initiating free-radical polymerization processes. The present study indicates the occurrence of significant termination by disproportionation in the polymerization of methyl acrylate. Additionally, it has been demonstrated the dicyclohexyl itaconate undergoes termination by disproportionation almost exclusively.
Impact and interest:
Citation counts are sourced monthly from and 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
