Real-Time Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy To Monitor Multiacrylate Polymerization Reactions

PEG-based hydrogel membrane coatings

“…Reaction conversion was gauged used ATR-FTIR [11,[16][17][18][19]. The FTIR spectrum of 100PEGDA matches with that previously reported in the literature [11].…”

“…Sharp peaks at 810, 1190, and 1410 cm À1 result from vibrations of the unreacted CdbndC bond in the acrylate endgroups; disappearance of these peaks indicates that the acrylate groups have reacted [12,[16][17][18][19]]. …”

On‐line Monitoring of Polymerization and Cure

“…Applications of FTIR spectroscopy to polymerization reactions include kinetic studies of laser-induced photopolymerization directly in a spectrometer [20], multiacrylate polymerization studies using a quartz crystal ATR device [21], and monitoring of carbocationic polymerization with ATR probes [22,23]. Crosslinking reactions in various resins have been studied by IR spectroscopy [24,25], and FTIR imaging using focal-plane array detection [26].…”

A New Model and Measurement Technique for Dynamic Shrinkage during Photopolymerization of Multi‐Acrylates

“…2 961 cm À1 was used as the internal reference. [15] The position of the Melinex film, and thus the thickness, L, of the underlying layer of acrylate, was monitored using a highprecision laser displacement meter LC-2401 (sensor head model LC-2430; from Keyence Co., Kyoto, Japan), with a displacement resolution of 0.32 mm. The meter was linked to a computer to record the displacement data.…”
