| As the solid-state polymerization has the features of lower active energy, high purity, the structure controlled by the molecule local regularity during the polymerization, without solvent in the course of the reaction and environment-friendly, it is widely applied in the fields of plastic, medical and health, molecule imprinting and micro-patterning. Self-assemble technology is an effective means to prepair collections of special structure and shape. In this article, we have got crystalline membrane of polyacrylamide and its derivatives which can't get in other traditional methods, by combining the self-assemble technology and solid-state polymerization.1. The crystallization of the acrylamide monomer on GN, PVA, PEG has been studied. It is found that we can get an orderly and better crystalline membrane when use gelatin as a film material in appropriate concentration and ratio of monomer. After irradiated, we use the IR, UV, GPC, DSC, XRD and other means to characterize the crystalline membrane. The relationship of irradiated time and the monomer residues, irradiated time and the molecular weight have been studied. The crystal membrane changes little after irradiation. By the SEM, we can found that the crystal surface orientation like fiber.2. The crystallization of the AMPS, MBA and NMA with the water-soluble macromolecular has been studied. The surface tension of the solution of the monomer and gelatin has also been studied. As AMPS for example, we use IR, UV, GPC to characterize the crystalline membrane after been irradiation. By SEM, little water in the crystalline membrane can be found.3. We prepair two water-soluble macromolecular by solution polymerization: PAMPS, P(AMPS-co-AA-co-AM). They are characterized by IR. The situation of crystallization of AM and its derivatives on the water-soluble macromolecular are been studied. The complex of AM and its derivatives crystaled on the gelatin layer are also been studied. |
