A resin composition is provided which comprises (A) 100 parts by weight of an ABS graft copolymer composed of an acrylonitrile compound and a vinyl aromatic compound in a weight ratio of 10:90 to 50:50, and (B) 5 to 30 parts by weight of an ethylene oxide copolymer admixed with the ABS graft copolymer and containing at least 50 wt. % of ethylene oxide, the ethylene oxide copolymer having a refractive index (nD²⁰) of at least 1.50. The composition, which has antistatic properties, is useful for injection molding to give moldings having an excellent surface appearance.
Novel propranolol analogues have been designed and synthesised and their enantioselective binding to the cellulose degrading enzyme, Cel7A, has been evaluated. Affinity and enantioselectivity have been determined by capillary electrophoresis experiments. Ligands with significantly improved affinity and selectivity have been obtained and an analysis of the results has led to insights concerning the relation between the changes in ligand structure and selectivity as well as affinity to the protein.
