SYNTHESIS OF HYDROXYL-TERMINATED POLYBUTADIENES USING GLYCOL ETHER SOLVENTS

摘要

SYNTHESIS OF HYDROXYL-TERMINATED POLYBUTADIENES USING GLYCOL ETHER SOLVENTS (D#80,906-F) Disclosed is an improvement in a process for polymerizing 1,3-butadiene selectively to form relatively low molecular weight hydroxyl-terminated polybutadiene oligomers in the presence of an aqueous solution of hydrogen peroxide which comprises the use of a glycol ether solvent to produce butadiene oligomers having a high degree of OH functionality and suppression of formation of solid or gel-type insoluble xubber by-products.
