## Abstract Novel gel systems demonstrating rhythmically pulsatile mechanical motion similar to that of a heartbeat were developed. Selfβoscillations of swelling and deswelling for the polymer hydrogels were realized by coupling pH and temperature sensitive hydrogels with a nonβlinear chemical reac

The osmotic deswelling of polymer networks swollen in a good solvent by transferring it into a solution of a linear polymer in the same solvent is investigated using the modified Flory model proposed previously. The predicted results obtained using this simple model are compared to the experimental
## Abstract Two sets of emulsion particles have been synthesized. In the first set, surfactant free emulsion was used to directly synthesize PSβPNIPAAM copolymer particles. In the second set, polystyrene particles with an ATRP initiator shell were first synthesized and subsequently grafted with PNI
## SYNOPSIS A series of novel superabsorbent copolymers of acrylamide (AM), sodium allylsulfonate (SAS), sodium acrylate (AA), and N,N'-methylenebisacrylamide (BisA) were synthesized using potassium persulfate (KPS)/N,N,N',N'-tertramethylethylenediamine (TMEDA) as the initiator. The influences of
