ABSTRACT:
Gravity flow in generally vertical stack lines in buildings and dwellings is improved by the application at the top of the drain of a concentrate of a water-soluble vinyl addition polymer, said concentrate being a water-in-oil emulsion which has a water-soluble vinyl addition polymer concentration between 20 and 50% by weight based on the total emulsion which exhibits unusual stability properties. The invention also applies to lubrication of garbage prior to its entry into garbage disposals.
