Title:
凝結促進作用を有する水中に再分散可能なポリマー粉末-組成物、その製法及びその使用
Document Type and Number:
Japanese Patent JP4646185
Kind Code:
B2
Abstract:
A water-redispersible polymer powder composition with a binder-accelerating effect is based on homo- or mixed polymers of monomers comprising vinyl esters, methacrylic acid esters and acrylic acid esters, vinyl aromatic compounds, olefins, dienes and vinyl halides, at least one protective colloid and one or more amine compounds. A water-redispersible polymer powder composition (I) with a binder-accelerating effect is based on homo- or mixed polymers of monomers comprising vinyl esters of optionally branched 1-15C alkyl carboxylic acids, methacrylic acid esters and acrylic acid esters of 1-15C alcohols, vinyl aromatic compounds, olefins, dienes and vinyl halides, at least one protective colloid, optionally antiblocking agents and one or more compouds of formula (1) or (2) or their corresponding salts. NR3 (1) R2N-(CH2)n-NR2 (2) R = H, 1-6C alkyl, hydroxyalkyl or polyalkylene glycols terminated by 1 or 2 NH2 groups with 1-6C alkylene groups An Independent claim is included for a process for the production of the water-redispersible polymer powder composition (I) by addition of the binder-accelerating components immediately prior to the spray drying of the corresponding polymer dispersion, cospraying in the salt form with the polymer dispersion to form the powder, or addition to the powder form after drying.
