Title:
POWDERY POLYMER AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3021865
Kind Code:
B2
Abstract:
PURPOSE: To provide a magnetized powdery polymer by polymerizing specific vinyl compounds with magnetic metal oxide using a radical-generating catalyst.
CONSTITUTION: A powdery polymer containing magnetized hydrophilic free radicals is prepared from a magnetic metal oxide and a copolymer expressed by the formula shown. In the formula, R is H, 1-4C alkyl, or phenyl; R1 is H or 1-4C alkyl; R2 and R3 are independently H, halogen, or 1-4C alkyl, or 1-4C alkoxy; R4 and R5 are independently 1-4C alkyl; X is alkyl sulfate ion, halogen ion, perchlorate ion, hydrogen sulfate ion, or p-toluenesulfonate ion; R6 and R7 are independently H, halogen or organic group. R and R1 to R7 may individually be different species; m and n are in mol.%, 0<m<20, 80<n<100, m+n=100.
