Title:
ポリマー粉末の製造方法
Document Type and Number:
Japanese Patent JP7413360
Kind Code:
B2
Abstract:
A process prepares a polymer powder, with a D50 particle size from 40 to 200 μm and a Hausner factor of 1.25 or less, by freeze drying and subsequent loosening up of an aqueous polymer dispersion containing 15 to 50% by weight of a polymer. The polymer is polymerized from 10 to 30% by weight of methyl methacrylate, 50 to 70% by weight of methyl acrylate, and 5 to 15% by weight of methacrylic acid.
