    摘要: A mixed phenyl/mesityl phosphate ester composition that is useful as a fire retardant additive, having a phosphorus content of from about 8.2% to about 8.4% is prepared by reacting with agitation at about 120.degree. C. to 130.degree. C. distilled still bottom phenols with phosphorus oxychloride in the presence of a Friedel-Crafts catalyst to form a reaction product containing a substantial quantity of monoaryl phosphodichloridate and diaryl phosphochloridate. This reaction product is then further reacted at an elevated temperature with sufficient phenol to form a triaryl phosphate ester mixture. The mixed phenyl/mesityl phosphate ester so obtained remains a liquid at room temperature over a substantial period of time.

    摘要: Flame retardant polyphenylene ether resin compositions are described in which the flame retardant agent is a mixture (by weight) of the following:(a) about 1.5% to about 3.0% of: ##STR1## (b) about 15.0% to about 20.0% of: ##STR2## (c) about 23.0% to about 28.0% of: ##STR3## (d) about 47.0% to about 56.0% of: ##STR4## wherein R.sub.1 and R.sub.2 are each selected from the class consisting of hydrogen, methyl and ethyl, it being understood that when one of R.sub.1 and R.sub.2 is hydrogen the other is ethyl and when one of R.sub.1 and R.sub.2 is methyl the other is methyl, the resulting two methyl groups being in the 2,4-, 2,5-, 2,3-, 3,4- and 3,5-positions, it being further understood that the ethyl groups are almost entirely in the meta (m) and para (p) positions.

    摘要: There is provided a process for preparing water-soluble polyelectrolytes by a water-in-oil emulsion process. A mixture of a surfactant, free radical initiator, at least one water-soluble, oil-insoluble, ethylenically unsaturated monomer adapted to polymerize under refluxing conditions, oil and water (the oil and water being adapted to form an azeotropic boiling mixture) is heated with vigorous agitation. The monomer polymerizes at the reflux temperature under the vigorous agitation with a concomitant simultaneous loss of water. Finely divided, water-soluble particles result.
