Title:
改良された分散特性を有する水溶性ポリマー粉末配合物
Document Type and Number:
Japanese Patent JP2014507549
Kind Code:
A
Abstract:
The present invention relates generally to water soluble polymer powder formulations, and more particularly, to a cellulose ether formulation which in powder form is suitable for direct addition to water-based systems to produce smooth, lump free solutions. The cellulose ethers are crosslinked with an aldehyde crosslinker and include a dry weak acid which slows hydrolysis of the hermiacetal linkage formed by the crosslinker. The selected acid does not adversely affect solubility stability.
