In order to eliminate unwanted interactions between catalysts and additives in polymerization reactions, one of the reactant streams is split into two parts, one which is mixed with additives, and the other with catalysts. The separation of these two parts eliminates the unwanted reactions between additives and catalysts prior to the polymerization reaction. In the case of polyurethane foam reactions, the reaction catalysts can be separated from additives that provide flame-block characteristics, such as expandable graphite. The two parts of the reactant stream are then recombined with the second reactant in specific ratios in order to achieve the desired polymerization reaction and resulting polymer product.
