【発明の名称】貯蔵安定性の水性重合体分散液及びその製法
Document Type and Number:
Japanese Patent JP2642142
Kind Code:
B2
Abstract:
The polymer dispersions are obtainable by dispersing a mixture of
15 - 50% by weight of a copolymer (A) comprising
(I) 1.5 - 15% by weight of copolymerisable compounds containing 3 to 10 carbon atoms and one carboxyl or carboxylic anhydride group,
(II) 30 - 98.5% by weight of C1- to C20-alkyl acrylates or methacrylates,
(III) 0 - 60% by weight of vinylaromatic compounds,
(IV) 0 - 20% by weight of copolymerisable carbonyl compounds,
(V) 0 - 20% by weight of further copolymerisable organic compounds not mentioned under (I) to (IV),
and 50 - 85% by weight of a copolymer (B) comprising
40 - 100% by weight of monomers (II) and
0 - 60% by weight of monomers (III) to (V),
with the proviso that the copolymers (A) and (B) together contain up to 65% by weight of alkyl (meth)acrylates (II) as synthesis component whose homopolymers have glass transition temperatures of below 0 DEG C, and that at least one of the copolymers (A) and (B) contains the monomers (IV) as synthesis component,
in water with addition of ammonia and a polyhydrazide (C).
The dispersions are used to produce paints and coatings.
