초록 ▼

A polymer emulsification process comprising intimately dispersing a liquified water insoluble polymer phase in an aqueous liquid medium phase containing at least one nonionic, anionic or cationic oil-in-water functioning emulsifying agent, in the presence of a compound selected from the group consisting of those hydrocarbons and hydrocarbyl alcohols, ethers, alcohol esters, amines, halides and carboxylic acid esters which are inert, non-volatile, water insoluble, liquid and contain a terminal aliphatic hydrocarbyl group of at least about 8 carbon atoms, and mixtures thereof, and subjecting the resulting crude emulsion to the action of comminuting forces sufficient to enable the production of an aqueous emulsion containing polymer particles averaging less than about 0.5 m

대표청구항 ▼

A polymer emulsification process comprising first intimately dispersing a liquified water insoluble polymer phase having a viscosity of less than about 10,000 cps in an aqueous liquid medium phase in an approximate polymer phase:aqueous phase weight ratio of 0.1:1 to 2:1 at a temperature of about 40°to about 90°C., said aqueous phase containing about 0.1 to about 5%, by weight of the water therein, of at least one nonionic, anionic or cationic oil-in-water functioning emulsifying agent, in the presence of about 0.2 to about 12%, by weight of said polymer phase, of a compound selected from the group consisting of those hydrocarbons and hydrocarbyl alcohols, ethers, amines, halides and esters which are inert, nonvolatile, water insoluble, liquid at said temperature and contain a terminal aliphatic hydrocarbyl group of at least about 8 carbon atoms, and mixtures thereof, and then subjecting the resulting crude emulsion to the action of comminuting forces sufficient to enable the production of a stable, sedimentation-resistant aqueous emulsion containing polymer particles averaging less than about 0.5min size.
