| Résumé : |
This technical paper presents information concerning a versatile aliphatic polycarbonate diol that has been developed by Perstorp and evaluated in aqueous anionic polyurethane dispersions. The comparison is made against polyurethane dispersions using the conventional macrodiols like polyether and polyester. This new class of polycarbonate macrodiols includes homopolymers derived from 2,2-dialkyl-l,3-propanediols.Films were cast from the aqueous polyurethane dispersions and evaluated according to different coating evaluation methods such as hardness, drying, solvent, acid and alkali resistance. This newly developed polycarbonate shows a high hardness, good drying property, excellent water, acid and base resistance. |
