Data analysis continuous polymer process

Apparatus. Since all the polymer modification reactions presented in this paper involved gas consumption, an automated gas consumption measuring system was designed, fabricated and used to keep constant pressure and record continuously the consumption of gas in a batch type laboratory scale reactor. Process control, data acquisition, and analysis was carried out using a personal computer (IBM) and an interface device (Lab-master, Tecmar Inc.). 

Heteronuclear chemical shift correlation techniques can be used to infer spin-lattice relaxation times of the protons attached to the observe nucleus (39). This is accomplished by saturation of the protons and observe nucleus followed by a variable time t (saturation recovery) during which the observe nucleus is continued at saturation (by repeated pulsing) and the attached proton remagnetizes. This process is followed by the normal H/X 2D shift correlation experiment. The t-dependence of the 2D peak intensities is then used to extract H T s by exponential analysis. This approach can be used to extract proton Ti s in polymers via observation of their attached obtaining motional data nor-...
