Simultaneous monitoring ACOMP

Simultaneous monitoring by in situ NIR spectroscopy and ACOMP was reported in the case of methyl methaaylate (MMA) polymerization reaction [6]. 

In this context, the use of ACOMP for the simultaneous monitoring of the evolution of coUoid phase (monomer droplets, polymer latex particles) and solution phase (polymer and monomer) characteristics during emulsion polymerization was recently reported as a versatile characterization tool that offers absolute, model-independent determination of quantities such as conversion, composition, and molecular weight [39],... 

The first use of ACOMP to follow in real-time ATRP reaction kinetics was recently reported [91]. The ACOMP multidetector platform allowed simultaneous monitoring of conversion, weight-average molar mass, M, and intrinsic viscosity, from which viscometric-average molar mass and MJM were computed, in the case of ATRP reactions of BA, initiated by methyl 2-bromopropionate (M2BP) and catalyzed by copper bromide. 

Recently, ACOMP capabilities were expanded to follow the evolution of different copolymer features during copolymerization reactions. A first study reported the online monitoring of the copolymerization of MMA and styrene [17]. Simultaneous, model-independent evolution of the average composition and mass distributions during free radical copolymerization reactions were determined. Also, model-dependent calculations of reactivity ratios and sequence length distributions were made. 

A new advance with regard to the instrumentation and methods available for online monitoring of heterogeneous polymerization reactions was made by using ACOMP for monitoring the evolution of multiple characteristics during polymerization. The information-rich data collected simultaneously by multiple detectors provide absolute, model-independent determination of quantities such as conversion, composition, and molar mass distribution and avoid potentially damaging effects of the reactor environment.
