Fundamental Measurements in Online Polymerization Reaction Monitoring and Control with a Focus on ACOMP

Abstract

Fundamental measurements in online polymerization reaction monitoring and control seek to avoid empirical and inferential models in data interpretation. One such approach making use of multiple detectors is automatic continuous online monitoring of polymerization reactions (ACOMP), wherein a continuous reactor stream is automatically, continuously diluted and conditioned to where measurements reflect intrinsic particle properties and not the interactions that can dominate measurements in concentrated media. Examples where dilute regime measurements are needed include static and dynamic light scattering, and reduced viscosity. This review focuses on ACOMP to illustrate a number of reaction contexts where fundamental measurements are used to gain a comprehensive picture of reaction characteristics.

Living Radical Polymerization by the RAFT Process – A Third Update

“…[561] On-line monitoring of RAFT polymerization has been performed using ACOMP (automatic continuous online monitoring of polymerization reactions). [221,439,562] This technique [543] (EA) [543] (EA/MMA/Am) [543] 'R'-connected…”

“…The method has been applied to study the homopolymerization of BA in butyl acetate, [439] the copolymerization of BA with MMA, [562] and the copolymerization of DMAEMA with styrene in DMF [221] all with RAFT agent 155.…”

Filtrodynamics: Time Dependent Trans-Filter Pressure Signals for Early Detection and Monitoring of Particulates During Chemical Processing

“…Signal/noise dimensions and sensitivity of filtrodynamics are not addressed here, but it is noted that filtrodynamic implementation in conjunction with a platform such as automatic continuous online monitoring of polymerization reactions, [17] can allow particulate dilution to any desired degree, to enhance sensitivity and/or to extend filter life. While experiments in this work show very good repeatability it is an open research question as to how the approach will work as it moves towards less ideal particle systems and more complex applications.…”

Polymers from Natural Products

“…In the last years, important progress has been reported [113][114][115]. As the synthesis of monomers and polymers from vegetable oils has several industrial applications, research in this area is widely explored.…”
