Abstract: The present invention is comprised of an at least one of at least two containers of equal of different dimensions, having a sidewall that forms a tubular or parallelogramic inner cavity. The sidewall is terminated or sealed at the top and bottom with a removable lid. The lid may be slightly different for a lid covering the uppermost container. Each removable lid is comprised of a horizontal covering surface having a rim or ribbon around its perimeter. The bottom rim forms a stand or a sealed means for attaching to a lower container, while the top rim, if present and engaged in a sealed association, forms a means for attachment to an upper container. The lid preferably further contains an opening to permit dispensing of contents being stored inside the cavity of the container. There may also exist a top terminal lid whose lid may contain only the just the internal coupler area which forms a tight seal around an upper lip of a container's sidewall.

Abstract: This invention is a process to manufacture high quality vinyl aromatic polymer that is essentially free of unreacted vinyl aromatic monomer using retarded anionic polymerization wherein the retardant is insoluble and can be removed from the polymerization at an intermediate stage so that the polymerization can be carried to completion in the absence of the retardant.
