In Situ NMR Monitoring of Living Radical Polymerization, that results in accurate information on the polymerization. An example is given whereby living radical polymerizations is studied in the presence of ethylene glycol groups in monomer, initiator and solvent. Methyl ether poly (ethylene glycol) macroinitiators of various sizes are shown to initiate l

Real-Time Monitoring of Isocyanate Chemistry using a Fiber-Optic FTIR Probe,on phase and in the form of urethane foams and binders, lends itself well to this approach. It is shown in this paper that the calibration of mid-IR fiber optics is simple and transferable between probes and probe heads, and that useful information about reaction rates and extent of cure can be obta

Real-Time Monitoring of the Components in PVC Melt Compounds Using NIR Spectroscopy During Extrusiomixture with the following composition: PVC (76%), recycled PVC material (10%), impact-resistant modifier (5%), lubricant (4%), TiO. (3%), CaCO. (2%). We varied the content of the modifier from 4.1 to 6.5% and the content of the lubricant from 2.8 to 4.5%. We developed a PLS model with a calibration

nd systems like voice-band telephone line modems. In 1970, a plain 9600 bps telephone line modem was the size of a big microwave oven and cost at least $15,000. Today the signal processing portion of a state-of-the-art V.34 28,800 bps modem can be bought as a set of two or three chips for about $40
