rate constants ( /2 "= 8 s) and thus the literature values quoted in this paper should be considered lower limits to the reaction rate for the conditions employed here (1 N NaOH).Acid-Catalyzed Hydrolysis of PE-COgCHg. Hydrolysis was carried out by floating PE-C02CH3 (ester side down) on the surface of 50% (w/w) H2S04 at 25 ± 2 °C for the specified time.The film was rinsed 4 times in water and once in acetone and air dried. Literature values for the hydrolysis rate were determined from the pseudo-first-order rate constants established under identical conditions.26Registry No. polyethylene,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
