AQUEOUS STARCH CONTAINING POLYMER DISPERSION FOR PAPER APPLICATIONS |
摘要 |
The invention concerns an aqueous starch-containing polymer dispersion obtainable by co-polymerisation of ethylenically unsaturated monomers comprising: (a) from 20 to 50 wt % of at least one of styrene or substituted styrene; (b) from 20 to 60 wt % t-butyl (meth)acrylate; and, (c) from 0 to 20 wt % of at least one ethylenically unsaturated co-polymerisable monomer being different from (a) and (b), in the presence of (d) from 10 to 50 wt % cationic starch, wherein the sum of (a)+(b)+(c)+(d) is 100%. The invention further concerns preparation and use thereof. |
