William C. Lehmann Ph. D.n acetyl groups. This is one of the main differences between algal and bacterial alginates. The acetyl groups play an important role in the physical–chemical properties of the alginates. To determine the influence of acetyl groups on the properties of alginates in solutions, seaweed alginates were a

William C. Lehmann Ph. D.o cross-linked swollen polymers. If a polymer solution is chemically cross-linked to a swollen polymer network (gel), the transport of a solvent in a gel in a centrifugal field consists of velocities due to sedimentation, diffusion and deformation. It was shown that the elastically active coefficien
