STABLE POLYMER LATEX AND PROCESS FOR MAKING SAME

摘要

The disclosed self-emulsified polyurethane polyurethane-polyurea latices are formed by chain extending in water a prepolymer which contains per molecule about two isocyanate groups at the ends of a chain and attached to some of the prepolymer chains a pendant group having at its remote end a salt-forming group or a hydrophilic group which produces the self-emulsifying characteristic.
