In this study, the key parameters affecting the synthesis and application of this adhesive were examined, and optimal conditions were identified. The water-dispersed PU adhesive was successfully synthesized, and applied in the fastness test of pigment printing on cotton fabric. The data demonstrated that all the fastnesses of PU adhesive were better than that of the conventional PA one.展开更多

RenaGel has been an example with remarkable success of a polymer synthesized to prevent the absorption of dietary phosphate for ESRD patients. Electrostatic interaction is the primary driving force for complexation of phosphate-based anions with these amino groups in the polymer backbone. Chitosan is a deacetylation product of chitin, which is the structural element in the exoskeleton of crustaceans and cell walls of fungi. The amino groups in the backbone give the phosphate binding ability to chitosan. This article has demonstrated that chitosan exhibited a phosphate binding effect indeed. Thus, it has potential applications in environmental management and wastewater treatment, as well as treatment of hyperphosphatemia patients.展开更多
