| titleOfInvention | Synthetic polymer latices and films and emulsion polymerization process |
| abstract | A synthetic vinyl or vinylidene polymer latex is prepared by carrying out the polymerization in the presence of an emulsifier which is a half-acid sulphosuccinate of the structure <FORM:1115571/C3/1> or <FORM:1115571/C3/2> where R is C6-C20 alkyl or mono (C8-C10) alkylsubstituted phenyl, M is hydrogen or a salt-forming radical, at least one M being a salt-forming radical, and n is 0 or a positive integer from 1 to 30. Compositions of the polymer latex and the sulpho-succinates are also claimed. In examples, vinyl acetate is polymerized and vinyl acetate and vinyl acetate and 2-ethylhexyl acrylate are copolymerized by a batch process, using sodium bicarbonate and potassium persulphate; vinyl acetate is polymerized by a continuous addition process; acrylonitrile, butadiene and styrene are copolymerized using potassium persulphate, dodecyl mercaptan, and tetrasodium pyrophosphate as a pH adjuster; butadiene and styrene are copolymerized using ammonium persulphate instead of potassium persulphate; butadiene, styrene and acrylic acid are copolymerized using tertiary dodecyl mercaptan, sodium acrylate solution, potassium persulphate and sodium hydroxide. Emulsifiers used in the examples are ones in which the ester group of the sulphosuccinate is an adduct of ethylene oxide and a C10-C14 or C10-C12 primary straight chain fatty alcohol or nonylphenol, a mixture of C12-C14 primary straight chain fatty alcohols or nonylphenol. In comparative examples the disodium salt of ester of sulphosuccinic acid and lauric monoethanolamide, sodium lauryl sulphate, alkyl benzene sodium sulphonate, disodium N-octadecyl sulphosuccinamate, sodium bis-(tridecyl) sulphosuccinate and ethylene oxide-octyl phenol adduct are used.ALSO:Half-acid sulphosuccinates of the structure <FORM:1115571/C2/1> or <FORM:1115571/C2/2> where R is C6-C20 alkyl or mono (C8-C10) alkyl-substituted phenyl, M is hydrogen or a salt-forming radical, at least one M being a salt-forming forming radical, and n is 0 or a positive integer from 1 to 30, are prepared by esterifying the appropriate alcohol with maleic anhydride and sulphonating, e.g. with sodium sulphite. |
