Abstract

Chain-length-dependent termination rate coefficients of the bulk free-radical polymerization of styrene at 80 °C are determined by combining online polymerization rate measurements (DSC) with living RAFT polymerizations. Full kt versus chain-length plots were obtained indicating a high kt value for short chains (2 × 109 L · mol-1 · s-1) and a weak chain-length dependence between 10 and 100 monomer units, quantified by an exponent of -0.14 in the corresponding power law (kt i,i) = kt 0 · P-b.

90 citations in Scopus
88 citations in Web of Science®
Search Google Scholar™

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.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
