Abstract: This invention relates to a distillation column for removing vinyl chloride monomer or other volatile material from an emulsion, suspension or dispersion containing such material. The apparatus comprises a column in which a series of inverted cones are mounted. The dispersion or emulsion is pulled downwardly over the cones and steam is fed into the column through sparges and flows upwardly against the descending stream of material. The low boiling materials are distilled out and recovered for reuse. The strips emulsion or dispersion are collected at the bottom of the column.

Abstract: An adhesive composition having particular reference to solution cast and hot melt adhesives comprised of an admixture of a tackifier and an unvulcanized block polymer product produced by the process of contacting conjugated diolefinic monomers mixed with a suitable amount of divinylbenzene under solution polymerization conditions with a polystyryl lithium catalyst.
