The propagation rate coefficient in free-radical bulk polymerization of butyl methacrylate has been studied at temperatures between -10°C and 60 "C up to a maximum pressure of 2000 bar. The data were obtained by means of the PLP-GPC technique which combines pulsed-laser polymerization with product a

## Abstract The propagation rate coefficient __K__~p~ of the free‐radical bulk polymerization of styrene is determined between 30 and 90°C up to a maximum pressure of 2800 bar. The data from pulsedlaser polymerizations and product analyses by gel‐permeation chromatography (PLP‐GPC) are adequately r
## Abstract Nitroxide‐mediated controlled/living radical precipitation polymerization of styrene in supercritical carbon dioxide has been performed using SG1 and AIBN as mediator and initiator, respectively. The equivalent bulk polymerization proceeded at a rate ≈1.58 times faster than the precipit
