POLYMER DISPERSIONS AND THEIR USE IN PIGMENTED COATING COMPOSITIONS |
摘要 |
A copolymer dispersion is described comprising a copolymer derived from a monomer mixture comprising: (a) 88.5 to 94% by weight of at least one vinyl ester of a saturated carboxylic acid; (b) 5 to 10.5% by weight of ethylene; (c) 0.5 to 5% by weight of at least one ethylenically unsaturated acid and/or an anhydride thereof and/or a salt thereof; and (d) 0.5 to 5% by weight of at least one ethylenically unsaturated monomer having at least one crosslinkable functional unit. The weight ratio of vinylester units to ethylene units in the copolymer is between 89:11 and 94:6 and the dispersion is stabilized with at least 1% by weight of an emulsifier, wherein the amounts of monomers and emulsifier refer to the total amount of monomers in the copolymer. |

1. A copolymer dispersion comprising a copolymer which is derived from a monomer mixture comprising:
a) 88.5 to 94% by weight of at least one vinyl ester of a saturated carboxylic acid; b) 5 to 10.5% by weight of ethylene; c) 0.5 to 5% by weight of at least one ethylenically unsaturated acid and/or an anhydride thereof and/or a salt thereof; and d) 0.5 to 5% by weight of at least one ethylenically unsaturated monomer having at least one crosslinkable functional unit,wherein the weight ratio of vinylester units to ethylene units in the copolymer is between 89:11 and 94 6, referring to the total amount of these units, the dispersion is stabilized with at least 1% by weight of an emulsifier, and the amounts of monomers and emulsifier refer to the total amount of monomers in the copolymer. |
