Time-temperature-transformation diagram for reactive processing of polyamide 12
In order to describe the different events occurring during the anionic polymerization of polyamide 12 (PA12), a general concept of a time, temperature, and transformation (TTT) diagram was established and related to reactive processing conditions. Polymeri ...
2001Star-shaped fluorescent polypeptides
Two series of novel, four-arm, star-shaped polypeptides were prepared via the ring-opening polymerization of γ-benzyl-L-glutamate N-carboxyanhydride and ε-benzyloxycarbonyl-L-lysine N-carboxyanhydride with a tetra-amino-substituted perylene fluorophore as ...
2001Inline conversion monitoring in MMA high solid content polymerization process
Thierry Meyer, Frédéric Lavanchy
Inline conversion measurements in chem. reactions are in general and esp. in polymn. reactions necessary for process monitoring and control. For polymn. monitoring, the sound propagation (UPV) can be related to the texture of the bulk with a high accuracy. ...
2001On-line conversion monitoring through ultrasound velocity measurements in bulk styrene polymerization in a recycle reactor - part I: experimental validation
Ultrasound propagates through an elastic medium at a rate or speed named the ultrasound propagation velocity (UPV). This velocity is detd. by the rate at which the wave energy is transmitted, inversely related to the square root of the d. and compressibili ...
2000Kinetic modeling of free radical polymerization of styrene initiated by the bifunctional initiator 2,5-dimethyl-2,5-bis(2-ethyl hexanoyl peroxy) hexane
Albert Renken, Thierry Meyer, André Rouge
This paper deals with the kinetic study of bulk free radical polymerization of styrene initiated with the commercial bifunctional initiator 2,5-dimethyl-2,5-bis(2-ethyl hexanoyl peroxy)hexane (Lupersol 256). The polymerization kinetics is investigated by D ...
2000Controlled polymerization of hexa-n-alkylcyclotrisiloxanes with long alkyl groups
Hexa-n-alkylcyclotrisiloxanes with side chains ranging from butyl up to decyl were polymerized anionically with cryptated lithium as the counterion. The polymerizations usually yielded polymers with low polydispersity, demonstrating the presence of a singl ...
1997Stabilization of colloidal palladium particles by a block copolymer of polystyrene and a block containing amide sidegroups
A block copolymer of polystyrene and poly(tert-butylmethacrylate) was prepared by anionic polymerization. The ester groups of the poly(tert-butylmethacrylate) were hydrolyzed, after which the remaining carboxyl groups were reacted with pyrrolidine. The res ...
1996Effect of periodic process execution on radical polymerizations
In the free-radical polymn. of styrene, a pulsed- or batch-type of polymn. process gave a higher space-time yield and efficiency than a stationary process at the same product mol. wt. and polydispersity. In the batch process, the range of av. mol. wt., con ...
