Quartz crystal microbalance study of the kinetics of surface initiated polymerization

Abstract

Surface initiated polymerization (SIP) is a valuable tool in synthesizing functional, and (v) the catalyst system (ratio among the ingredients, metal, ligands, and additives). The dynamic nature of IE is also described by these two variables, IE = a/(a + bt). Instead of the molecular weight and the polydispersity, we suggest that film thickness, the two kinetic parameters (a and b), and the initial density of the initiator and IE be the parameters that characterize ultrathin polymer brushes. Besides the kinetics study of SIP, the reported method has many other applications, for example, in the fast screening of catalyst system for SIP and other polymerization systems.surface initiated polymerization, quartz crystal microbalance, kinetics, controlled living radical polymerization

PET/PP blending by using PP‐g‐MA synthesized by solid phase

“…To enable a quantitative study of the in situ kinetics of the SI‐ATRP of MMA, homogeneity of the reaction medium is crucial to avoid unintended effects on the measured frequency and dissipation changes in the QCM‐D technique. Previously, a methanol–water solvent mixture was employed in QCM‐D studies of SI‐ATRP 22. Unfortunately, the same solvent mixture is far from being optimal in the study of a hydrophobic monomer such as MMA, not to mention the complications arising because of the occurrence of disproportionation of copper(I) halides in aqueous medium 23, 24.…”

“…2) Scheme c: state 1 > state 2 > state 4 was conducted in a continuous mode, while from state 4 to state 3 was in a discontinuous mode. Typical cases are by SIP23 or biopolymer adsorption to the surface 20. In the discontinuous mode, the QCM chip has to be unmounted from the sensor, which will lead to frequency variation but this can be minimized and is negligible for most applications 5.…”
