Tværbundne, vandopløselige polymerdispersioner

Prepn. of low viscosity water-soluble polymer dispersion comprises mixing a monomer component in aq. soln. with at least one polymeric dispersing agent. The monomer component comprises: (a1) 50-99.99 wt.% of at least one water-soluble monomer; (a2) 0.01-5 wt.% of a cross-linkable N-methylol cpd.; (a...

Beschreibung
Zusammenfassung:	Prepn. of low viscosity water-soluble polymer dispersion comprises mixing a monomer component in aq. soln. with at least one polymeric dispersing agent. The monomer component comprises: (a1) 50-99.99 wt.% of at least one water-soluble monomer; (a2) 0.01-5 wt.% of a cross-linkable N-methylol cpd.; (a3) 0-1 wt.% of at least one cross-linking monomer with at least two unsatd. ethylenic radically polymerisable gps.; and opt. (a4) 0-30 wt.% of at least one hydrophobic monomer; and (a5) 0-20 wt.% of at least one amphiphilic monomer. The resulting polymerisate has a mol. wt. (Mw) of ≥ 5 x 10 Daltons and is incompatible with the dispersing agent.
