Polystyrene (PS) was copolymerized with methyl methacrylate (MMA) and/or glycidyl methacrylate (GMA) through ultrasonic irradiation. Block copolymers PS-b-PMMA, PS-b-PGMA and PS-b-P(MMA-co-GMA) were obtained; their compositions were determined by FTIR and ~H-NMR. The variation of MMA content in PS-b

## Abstract Lineweaver‐Burk plots of reaction rate data obtained with immobilized enzymes need not be linear even when intrinsic enzyme kinetics follow the simple Michaelis‐Menten rate expression. Theoretical calculations show that mass transfer effects may cause curvature which is concave or conve
