Abstract

Pulsed laser polymerization (PLP) combined with size exclusion chromatography (SEC) is the method of choice for determining propagation rate coefficients. The influence of the longchain branching in PLPÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“SEC is investigated using multiple-detection SEC and a recently developed method to detect long-chain branching [P. Castignolles, R. Grab, M. Parkinson, M. Wilhelm, M. Gaborieau, Polymer 2009, 50, 2373.] While little or no long-chain branching is detected in poly(n-butyl acrylate), the error in relevant molecular weights of poly(2-ethylhexyl acrylate) is large (30ÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“100%) due to long-chain branching. Possible variations of propagation rate coefficient with alkyl groups in alkyl acrylates or with the solvent have to be reconsidered.
