Preparation and characterization of thermoplastic water-borne polycarbonate-based polyurethane dispersions and cast films

Popis výsledku v původním jazyce

Stable water-borne polyurethane dispersions (PUDs) were prepared from bifunctional aliphatic polycarbonate-based macrodiol, 2,2-bis(hydroxymethyl)propionic acid (DMPA), 1,6-diisocyanatohexane, 1,4-butanediol (BD), and triethylamine. Water-borne dispersion particles are thus solely formed from self-assembled linear PU chains. Both PUDs and PUD-based films were characterized with regards to the concentration of DMPA (ionic species content) and BD (hard-segment content). Average particle size of PUDs decreased and their long-term stability increased with increasing DMPA and decreasing BD concentration. Functional properties of cast films made from PUDs are substantially influenced by the character of the original colloidal particle dispersions. The swelling behavior of the films, their surface morphology, and mechanical properties are more influenced by DMPA than BD contents. At DMPA concentrations higher than 0.2 mmol g1 of the solid mass of polyurethane, distinct self-organization of in
