A study has been conducted on the origin of the molecular weight (MWT) dependence of the apparent interdetector-delay (IDD) in multidetector size exclusion chromatography (SEC). The IDD–MWT relationship proved to be independent of polymer concentra

Catalytic chain transfer polymerization (CCTP) of methacrylates is an efficient method to produce low molecular weight poly(methacrylates). The mechanism is such that the products each have a terminal vinyl group which is then available for subsequen
