摘要：
Polyurethane dispersions (PUDs) are one such class of coatings that comply well with stringent VOC regulations. In this study, PUDs were prepared as aqueous dispersions using a new highly versatile crosslinkable anionomer, 2-acrylamido 2 methylpropanesulfonic acid (ATBS), which is commercially available, yet not explored by the coating industry. The influence of this novel anionomer on the performance properties of polyurethane resins was evaluated by comparing performance/properties of this newly synthesized PUD with dispersion based on conventional anionomer, DMPA. Analyses of their physico-chemical and thermo-mechanical properties revealed that PUD based on ATBS showed comparatively much better thermal, mechanical, and chemical and coating properties than the PUD based on DMPA anionomer.
