Title:
加水分解性粒子
Document Type and Number:
Japanese Patent JP6834117
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide hydrolyzable particles which have hydrolyzability, circularity and a particle size that are suitable for hydraulic fracturing, are easy to be handled, and hardly cause fusion between particles.SOLUTION: Hydrolyzable particles have such a dispersed structure that fine particles of a hydrolyzable polymer for adjusting hydrolyzability of a hydrolyzable matrix resin are distributed in the matrix resin, and have such circularity that an average particle diameter (D) is in a range of 300-1,000 μm and a ratio of minor axis/major axis is 0.8 or more.SELECTED DRAWING: None
