NFPA-ACRYLIC ACID COPOLYMERIZATION CHARACTERISTICS AND PROCESS DEVELOPMENT

Abstract

This report discusses continued efforts to improve the process for making NFPA-acrylic acid copolymers and to characterize the product. Particular emphasis is directed toward developing, experimentally testing, and utilizing mathematical models of the process. The scope of the work includes considerations of compositional uniformity, molecular-weight distribution, and polymerization rate of the copolymer. A new process whereby the comonomers are added incrementally is described which greatly increases the productivity of the reactor and permits control of molecular weight. Propellant made from copolymer prepared in this manner has improved physical properties, fissuring characteristics, and physical-property aging characteristics.
