In this technical note we will demonstrate the use of active feedback control with Lab ACOMP to directly control polymer molecular weight by adjusting the monomer feed into the reactor. By integrating ACOMP with a feedback controller, molecular weight is directly controlled, something previously not possible in polymerizations.Read More
Using ACOMP in an industrial environment allows for improved polymer quality control of production processes and material properties. With the benefit of an online, real-time analysis provided by ACOMP, plant operators can take corrective actions to change QC parameters or even halt the reaction if the product properties are deviating too much.Read More
ACOMP provides a real-time, online analysis of polymerization reactions. This technical note describes how ACOMP can track the properties of polyacrylamide produced with different initiator types and concentrations. This note compares the effects of initiator type and concentration in the synthesis of polyacrylamide, a specialty polymer with many industrial applications.Read More
This technical note demonstrates the use of ACOMP to monitor two types of polyurethane polymerizations, the industry standard and a novel type using a non-toxic isocyanate monomer. The ACOMP system can monitor in real time the intrinsic viscosity and molecular weight for the stepwise polymerization reaction that occurs.Read More
ACOMP was used to continuously measure the anionic polymerization of solution styrene butadiene rubber. ACOMP successfully tracked conversion, along with weight-average molecular weight (Mw), and low and high shear reduced viscosities (RV), including during the coupling reaction.Read More
This technical note describes the use of ACOMP to monitor polymerization kinetics, intrinsic viscosity and Mw in a very common system for producing pressure sensitive adhesives, which uses the acrylic comonomers acrylic acid (AA) and 2-ethylhexyl acrylate (2EHA).Read More
Understanding the thermal, chemical and mechanical stability and physical properties of polymers is essential for development success. The case studies below outline the experimental methodologies and data analysis using ARGEN™ to monitor polymer degradation and to characterize molecular weight as well as the effects of temperature, shear stress and solution conditions on the stability of...Read More
