Abstract: A preferred process for producing a brominated, non-fused aromatic composition involves a continuous bromination in a continuous, mixed reactor such as a continuous stirred tank reactor. Bromine and the aromatic substrate, and optionally a bromination catalyst, are continuously fed to a reaction zone to form a reaction mixture, and the reaction mixture is continuously withdrawn from the reaction zone after an established average residence time. Bromination levels can be readily controlled by controlling the average residence time of the reaction mixture within the reaction zone. Preferred continues processes also provide mixed, brominated compositions having product distributions which are substantially broader than that obtained by batch brominations conducted to achieve the same level of bromination. Preferred products thus have broad melting ranges which are advantageous in compounding operations.

Abstract: A hydrophilic coating composition used to impart increased lubricity and wettability to the surface of a hydrophobic substrate which is comprised of three essential components:1) Hydrogel-forming polymer component A2) Water-soluble polymer component B3) Common solvent C for the components A and BThe water-insoluble, hydrogel-forming component A consists of a segmented copolymer with long, hydrophilic terminal blocks and the essentially hydrophobic central section. The two polymer components A and B have a limited miscibility in the absence of a common solvent C. Therefore, their blend tends to separate spontaneously into two polymer phases.
