Abstract: A constant composition copolymer is automatically made by means of a self-regulating batch process by maintaining the polymerization system at a constant volume throughout the reaction by adding polymerizable monomer in such a manner as to maintain both the unpolymerized monomer in the polymerization mixture at the original composition and the polymerization mixture at the original volume. The process is applicable to any polymerization reaction where a polymer is formed from two or more monomers and where a reduction in the volume of reaction mixture occurs during polymerization.
