Abstract
In an exemplary embodiment, the method includes the steps of providing an array of reaction vessels and providing a plurality of homogenous reaction mixtures within the reaction vessels. Each mixture comprises monomers at least partially embodied in a liquid and is provided in an amount sufficient to form a film having a thickness sufficient to allow the reaction rate of the polymerization reaction to be essentially independent of mass transport. Polymerization then takes place in the presence of a catalyst at reaction conditions effective in substantially maintaining the homogeneity of the reaction mixture. In this manner, polymerization can take place quickly and efficiently without stirring the reactants. The method is highly useful for testing reactants, catalysts, and associated reaction parameters.
