The structure-property relationships of water-dispersed polyurethanes based on tetramethyl xylene diisocyanate
Novel water-dispersed polyurethanes based on tetramethyl xylene diisocyanate (TMXDI), polycaprolactone or polytetramethylene glycols and alipbatic diamine chain extenders were synthesised. 2,2-bis(hydroxymethyl) propionic acid (DMPA) and triethylamine (TEA) were used respectively as potential carbox...
