dispersions of amorphous unsaturated polyester resins based on particular, urethanisierter dicidolisomerer

摘要

Aqueous polyester dispersion comprises an amorphous unsaturated polyester resin produced from an alcohol component comprising 10-100 mole % dicidol isomers; an acid component comprising 20-100 mole% alpha,beta-unsaturated carboxylic acid (I) and 0-80 mole% other carboxylic acid (II); and an isocyanate (III). Aqueous polyester dispersion comprises an amorphous unsaturated polyester resin produced from: an alcohol component comprising 10-100 mole % dicidol isomers; an acid component comprising 20-100 mole% alpha,beta-unsaturated carboxylic acid (I) and 0-80 mole% other carboxylic acid (II); and an isocyanate (III). The dicidol isomers comprise 20-40% each of 3,8-, 4,8- and 5,8-bis(hydroxymethyl)tricyclo(5.2.1.02.6)decane to a total of 90-100%. The dispersion has a solids content of 20-60 wt.%, a solvent content of 0-60 wt.%, a pH of 5.0-9.5 and a 20 degrees C viscosity of 20-500 mPa.s. An Independent claim is also included for production of such dispersions by reacting the alcohol component with (I) and (II) at 150-270 degrees C and then with (III), neutralizing the resin and dispersing it in the aqueous phase.
