HOMOGENEOUS TERPOLYMERS OF VINYL PYRROLIDONE, A QUATERNARY AMMONIUM MONOMER AND A HYDROPHOBIC MONOMER

摘要

A homogeneous polymerization process is described for making substantially homogeneous terpolymers of, by weight, 55-99 %, preferably 65-95 % of vinyl pyrrolidone; 0.5-49 %, preferably 1-25 % of a quaternary amino monomer, preferably 3-methacrylamidopropyl trimethylammonium chloride; and 0.5-49 %, preferably 1-25 %, of a hydrophobic monomer, preferably octadecyl methacrylate. The homogeneous terpolymer provides dual hair styling and conditioning functions in hair care applications.
