摘要： Improved flame retardant latex coatings are disclosed which comprise copolymers of ring-halogenated aromatic monomer units and alkyl acrylate/methacrylate monomer units, and which may additionally include at least one other monomer. In a first embodiment, the coatings include ring-brominated aromatic monomer units and alkyl acrylate and/or alkyl methacrylate monomer units. In a second embodiment, the coatings include these first two types of monomer units and further include third monomer units from unsaturated esters of saturated carboxylic acids, halogen-free aromatic monomers or unsaturated carboxylic or dicarboxylic acid monomers. In a third embodiment, the coatings include four monomer units, namely ring-brominated aromatic monomer units, alkyl acrylate/methacrylate monomer units, halogen-free aromatic monomer units and unsaturated carboxylic or dicarboxylic acid monomer units. In one aspect, the halogenated aromatic monomers are present in an amount to provide from 7 to 20 weight percent bromine in the final latex coating. In another aspect, the halogenated aromatic monomers include polybrominated monomers, particularly to provide monomers having an average of at least about 1.5 bromines per monomer unit. The coating polymers have glass transition temperatures in the -30.degree. C. to 30.degree. C. range and are useful, for example, for coating, paint, adhesive, sealant and non-woven binder applications.

摘要： A device for dispensing metered amounts of fluid under pressure from a single supply line to multiple distribution outlets having a pair of flow-directing cylinders with driven pistons connected by pipes to a pair of metering cylinders with free pistons so that when the driven pistons are at one end of their travel, fluid flows from the single supply line through the center of one of the driven pistons, through a pair of holes in the wall of the piston and the cylinder and into one end of each of the metering cylinders, thereby driving the free piston and the fluid in front of it toward the other end of its travel, the exiting fluid flowing through a pair of holes in the cylinder wall of the other flow-directing cylinder, around a pair of radial recesses in the outer wall of the driven piston therein and out another pair of oppositely positioned holes in the cylinder wall to a pair of distribution outlets; this action being reversed when the driven pistons are at the other end of their travel.
