Growth coefft. determn. for homo- or co-polymerisation - by chromatographically determining chain length distribution or molar mass distribution and using data to analyse coefft.
Growth coefft. determn. for homo- or co-polymerisation - by chromatographically determining chain length distribution or molar mass distribution and using data to analyse coefft.
Direct determn. of growth coeffts. during radical homo- or copolymerisation, includes carrying out radical polymerisation, induced by UV light pulses, determining the chain length distribution or molar mass distribution by chromotographic techniques, and determining the growth coeffts. by analysing the chain length distribution or molar mass distribution, taking into account the kinetic model of the polymerisation reaction. A flash bulb is used to generate the UV light pulses. USE/ADVANTAGE - The process is efficient and economical.
