The problem of shelf-life of polymerizable compounds is dealt with in conjunction with the problem of their processing. Kinetic parameters that characterize the polymerization of such compounds under storage conditions and the monomer processing have been analysed. Feasibility of a complex approach to the problem of shelf-life and processing of polymerizable compounds is shown using the example of the application of weak antioxidants. By increasing the antioxidant concentration the stability of the monomer is raised and the use of weak antioxidants facilitates monomer processing. The possibility to optimize the solution of problems connected with shelf-life of monomers and their processing has been shown. Values of parameters that characterize oxidative polymerization of methyl methacrylate, inhibited by several weak antioxidants have been determined along with the corresponding stoichiometric constants. The stoichiometric coefficient of an antioxidant has been found to depend on its concentration and on the rate of initiation. |
