Claims
- 1. A clear, stable aqueous or alcohol solution of (a) between about 10 and about 70 wt. % based on total composition of a copolymer derived from about 40 to about 80 wt. % of a N-vinyl heterocyclic monomer having from 3 to 6 ring carbon atoms and from about 60 to about 20 wt. % of a vinyl comonomer and (b) between about 0.02 and about 2 wt. %, based on copolymer of a nitrogen containing, trivalent boron complexed compound.
- 2. The solution of claim 1 wherein the N-vinyl heterocyclic monomer is N-vinylpyrrolidone or N-vinyl caprolactam optionally substituted on a ring carbon atom with methyl.
- 3. The solution of claim 2 wherein the N-vinyl heterocyclic monomer is N-vinylpyrrolidone.
- 4. The solution of claim 1 wherein said comonomer is selected from the group consisting of a C.sub.1 to C.sub.4 alkyl vinyl ester, acrylonitrile, styrene and mixtures thereof.
- 5. The solution of claim 4 wherein said comonomer is vinyl acetate and the weight ratio of monomer to comonomer is between about 50 and about 80 wt. % heterocyclic monomer to between about 50 and about 20 wt. % vinyl acetate.
- 6. The solution of claim 5 wherein the weight ratio is 55-70 wt. % N-vinylpyrrolidone to 45-30 wt. % vinyl acetate.
- 7. The solution of claim 1 wherein said boron complexed compound is a borane selected from the group of borane-ammonia, borane C.sub.1 to C.sub.4 alkyl amine, tetra C.sub.1 to C.sub.4 alkyl ammonium octahydrotriborate, morpholine-borane, C.sub.1 to C.sub.4 alkyl morpholine-borane, silylamino borane and mixtures thereof.
- 8. The solution of claim 7 wherein said borane complex is an organic compound.
- 9. The solution of claim 8 wherein said borane complex is tetramethyl ammonium octahydrotriborate.
- 10. The solution of claim 8 wherein said borane complex is borane-tertiary butyl amine.
- 11. The solution of claim 7 wherein said borane complex is borane-ammonia containing from about 0.005 to about 1 wt. % of an organic acid.
- 12. The solution of claim 11 wherein said organic acid is acetic acid.
- 13. The solution of claim 1 wherein said nitrogen containing trivalent boron complexed compound is between about 0.05 and about 0.2 wt. % of the copolymer.
- 14. A personal care formulation containing an effective film-forming amount of the solution of claim 1.
