Abstract: THIS INVENTION RELATES TO A NOVEL PROCESS FOR THE PREPARATION OF 2-SUBSTITUTED CYCLIC IMINOETHERS. MORE PARTICULARLY THIS INVENTION RELATES TO A NOVEL PROCESS FOR THE PREPARATION OF 2-SUBSTITUTED OXAZOLINES AND OXAZINES BY THE VAPOR PHASE CYCLODEHYDRATION OF N-(W-HYDROXYALKYL)-AMIDES IN THE PRESENCE OF A CATALYST. THESE COMPOUNDS ARE VALUABLE INTERMEDIATES FOR THE PREPARATION OF USEFUL POLYMERS.

Abstract: AN IMPROVED HAIR DRESSING FORMULATION CONTAINING (A) FROM ABOUT 0.1 TO ABOUT 10 WEIGHT PERCENT OF A WATERDISPERSIBLE POLYMER HAVING A REDUCED VISCOSITY RANGING FROM ABOUT 0.5 TO ABOUT 5.0 AS DETERMINED ON A 0.52 WEIGHT PERCENT SOLUTION OF POLYMER IN META-CRESOL AT25*C., SAID POLYMER BEING SELECTED FROM THE GROUP CONSISTING OF HOMOPOLYMERS AND COPOLYMERS OF MONOMERS OF THE FORMULA:

2-R-4-OXAZOLINE

WHEREIN R IS A SUBSTITUENT SELECTED FROM THE GROUP CONSISTING OF

CH3-, C2H5-, CH3-(CH2)(N-1)-COO-(CH2)M-,
