Abstract: A substantially agglomeration-free, finely divided catalyst component which is suitable for use as a cocatalyst with organoaluminum compounds in the polymerization of alpha olefins, which is formed by grinding a titanium trichloride material, an effective amount of an electron pair donor compound to enhance the performance of said catalyst component, and an effective amount for agglomeration control of an agglomeration control agent. The agglomeration control agent is effective in either reducing the attractive forces between the finely divided particles in the catalyst component or by preventing the close approach of these particles which would result in agglomeration.

Abstract: A process for producing tert-butylphenyl diphenyl phosphate which is stable at low temperature by a process wherein phenol is butylated to produce tert-butylphenol which is isomerized to produce mixed meta and para isomers thereof, and which thereafter is alkylated with isobutylene to produce tert-butylphenol having a C.sub.4 /.phi. ratio of about 0.62. The tert-butylphenol is then phosphorylated to the tert-butylphenyl diphenyl phosphate meta/para mixture with phosphorus oxychloride. The disclosed process provides a tert-butylphenyl diphenyl phosphate which will not freeze or gel at low temperatures.

Abstract: A process is provided for separating gaseous phosphorus trichloride from a gas stream. The process comprises contacting the gas stream with a condensing amount of liquid phosphorus trichloride to c ondense a portion of the gaseous phosphorus trichloride to liquid phosphorus trichloride. The liquid phsphorus trichloride is then separated from the gas stream. A process apparatus is also provided. The process is particularly useful in preventing or reducing the discharge of gaseous phosphorus trichloride to the atmosphere due to the accidental discharge of a high volume gas stream from a phosphorus trichloride reaction vessel.
