Japanese Patent JP2002524630

Kind Code:

A

Abstract:

Mannich polyols having a viscosity of from 300 to 3,500 cps (0.3 to 3.5 Pa*s) at 25° C. are prepared by admixing a phenol, an alkanolamines, and formaldehyde mixed in molar ratios of from 1:1:1 to 1:2.2:2.2 resulting in an initiator which can be alkoxylated using a mixture of ethylene oxide and propylene oxide to prepare polyols that have a nominal functionality of from 3 to 5.4.
