Kinetics of the anionic polymerization of caprolactam (CL) in microdispersion was investigated at temperatures between 90 and 130脗掳C and at stirring rates between 500 and 2000 rpm, respectively. For the investigated range of temperature data analysis showed pseudo-first order kinetics with respect ...
Herein is reported a novel dynamic kinetic reactor model for the living anionic solution polymerization of styrene/butadiene/divinylbenzene in a continuous stirred tank reactor train. The model accounts for association of the n-butyllithium, the anionic initiator, and the formation of tetrafunctional ...
The effects of different annealing time/temperature regimes on the thermal and crystalline behaviour of a series of statistical copolyamides (nylon 8/nylon 12), prepared by activated anionic polymerization of octanelactam/laurolactam (OL/LL), were determined by DSC, X-ray (WAXS), density and ...
The degree of polymerization (DPn), as determined by nuclear magnetic resonance spectroscopy, was for En, n = 22 (molecular weight (MW) = 3300) and n = 51 (MW = 7700) and for Kn, n = 21 (MW = 4400) and n = 55 (MW = 11,500). Aqueous solutions were prepared and filtered ...
Cationic Lignin Preparation Lignin-METAC was prepared in an aqueous heterogeneous reaction by the free radical polymerization of kraft lignin and METAC under mild acidic condition initiated by K2S2O8. During this reaction, METAC monomers, which contain cationic quaternary ammonium groups, were ...
Poly-L-Lysine (PLL) (with a degree of polymerization DPn = 50, corresponding to a molar masse of 8200 g/mol and a polydispersity index 1.04) was supplied by Alamanda Polymers (Huntsville, AL, USA). DGL (G2, G3, and G4) (batch numbers; DC 120902, DC 120103, DC 130604, ...

The shape of the curve illustrating the changes of conductivity during the polymerization reaction for the system P-005 was similar to the shape of the analogous graph plotted for the P-01. However, there were clear differences in the duration of the individual polymerization stages. For the P...
