The Use of Computers to Study the Penultimate and the Charge-Transfer Polymerization Models.
Abstract
Three programs have been written for evaluating the charge-transfer copolymerization model when operating in competition with the terminal model. The first program (Program CT-1) permits the calculation of r(1), r(1c2), r(1c2), r(2), r(2c2), r(2c1), and K from composition-conversion data. The second program (Program CT-2) allows one to design the optimum concentrations of M(1) and M(2) to use in experimental work. The third program (Program CT-3) calculates the copolymer composition, at any conversion, using charge-transfer model equation in the most general case. The need for a nonlinear solution is discussed and a nonlinear approach is used which simultaneously permits an objective analysis of the reliability of the method. The sensitivity of predictions to errors in polymer composition and percent conversion were investigated. Finally, it was demonstrated that no adequate composition-conversion data exists in the literature which can be used to test for a combined-charge-transfer and terminal model copolymerization. The method developed in this paper provide the guide necessary for obtaining such data.
