## Abstract A chromotropic acid‐functionalized polyurethane foam has been developed for use in an on‐line preconcentration system for cobalt and nickel determination. The packing material was prepared by covalent coupling of chromotropic acid with the polyurethane foam through an azo group. Co and
A stepwise temperature-and pressure-scanning thermal analysis method was developed to measure glass-transition temperature T g in the two-phase polymergas systems as a function of gas pressure p, and was used to confirm recent theoretical predictions that certain polymer-gas systems exhibit retrogra
