Abstract: Blends of aromatic carbonate polymers with glycidyl methacrylate grafts on ethylene-propylene-diene modified elastomer (EPDM) further modified by reaction with an epoxy acrylate have low glass as well as improved impact strength and strong weldlines.

Abstract: An antifoam composition is introduced as an aerosol into the main gas stream entering a gas-liquid separation tower. The main gas stream carries the small aerosol particles up the tower through the sieve-like separation trays and the water moving over the plurality of trays. The movement of the antifoam carried in the gas stream to the top of the tower is many times more rapid than the transit of liquid down the tower in countercurrent movement thereto. For antifoam particle sizes in the preferred range, movement of the antifoam continues unabated through a long series of trays in the tower to effectively inhibit foam formation therein.
