Claims
- 1. In a process for preparing polymers of chloroprene by emulsion polymerization using from about 0.05 to 2.0 parts by weight per 100 parts of polymerizable monomers of an octyl sulfate emulsifying agent selected from the group consisting of alkali metal octyl sulfates, ammonium octyl sulfates and mixtures thereof and washing of the resultant polymer with water to remove soluble emulsifying agents, the improvement comprising using as a stabilizer an alkylated diaryl amine.
- 2. The process of claim 1 wherein the said alkylated diaryl amine is an alkyl phenyl amine.
- 3. The process of claim 1 wherein the said alkylated diaryl amine is an octyl phenyl amine.
- 4. The process of claim 1 wherein the said alkylated diaryl amine is a mixture of monoalkyl diphenyl amine and dialkyl diphenyl amine.
- 5. The process of claim 1 wherein the said alkylated diaryl amine is a mixture of monooctyl diphenyl amine and dioctyldiphenyl amine.
- 6. The process of claim 1 wherein the said alkyl groups each have from one to 12 carbon atoms.
- 7. The process of claim 1 wherein said alkylated diaryl amine is present in an amount of from 0.005 to 2.0 parts by weight per 100 parts by weight of said chloroprene polymers.
- 8. The process according to claim 1 carried out without using salts of the condensation products of naphthalene sulfonic acids and formaldehyde.
- 9. The process of claim 8 wherein said octyl sulfate emulsifying agent is an alkali metal octyl sulfate.
- 10. The process of claim 9 wherein the said polymerization is conducted employing as an emulsifying agent a disproportioned wood rosin.
