Polyglycol esters

Surface-active polyglycol esters of alkanephosphonic acids are also formed by reaction of long-chain alkanephosphonic acids with olefin oxides, e.g., ethyl-enene oxide or propylene oxide. The reaction may be carried out in an autoclave or at atmospheric pressure, and the temperature may be varied between... 

Cationic accelerants vary in their efficacy [161]. Other types of accelerant have also been evaluated. In one study [162], comparisons were made between tetra-ethylammonium bromide, benzyltriethylammonium chloride, polyfdiallyldimethylammonium chloride) and the diethyldimethylammonium derivative of a benzenesulphonate polyglycol ester. It was found that the cationic polymers had a greater effect than the simple quaternary ammonium compounds of lower molecular mass. This effect was attributed to the capability of the polymers to enter into hydrophobic interaction with the fibre surface. Ethylenediamine has also been found to accelerate the alkaline hydrolysis of polyester [163]. 

Elastomers resulting from a series of organic reactions, e.g., a polyglycol ester of adipic acid reacted with an aromatic diisocyanate and cured with water, glycol or further reaction with an aromatic diisocyanate. These elastomers have high tensile strength, very high abrasion resistance, and lower hysteresis than natural rubber. A major use is in the manufacture of foamed polymers. 

From the various emulsifiers examined, an anionic emulsifier from the sulphonic acid group of polyglycol-ether of fatty alcohol and alkylphenol-polyglycol esters was used. The best results were achieved with the use of alkylphenol-polyglycol ester (Berol EMU27).

Emulsion breakers are typically specific for site or crude-oil type. Conventional emulsion breakers are most commonly formulated from the following types of chemistries polyglycols and polyglycol esters, ethoxylated alcohols and amines, ethoxylated resins, ethoxylated phenol formaldehyde resins, ethoxylated nonylphenols, polyhydric alcohols, and sulfonic acid salts. Commercial emulsion breakers may contain but one type of active ingredient or intermediate or a variety of intermediate types.

Tbe efficiency of difenzoquat depends directly on the kind and concentration of the surfactant in the aqueous spray. The best wild oat control has been obtained with a nonionic emulsifier of alkyl polyglycol ester type, in a quantity of O.S%, (in reference to the spray solution). In the factory formulation (Avenge) the proportions of the active substance and of the surfactant are adjusted to give the optimal effect in the recommended dose and the recommended quantity of spray solution. Avenge 200 contains 200 g of active substance plus 400 g of surfactant in each litre. Five litres of this solution is reconunended for a 4001/ha spray solution. Avenge 250 g contains 250 g of active substance and 200 g of surfactant in each litre, and its recommended dose is 4 in a 2001/ha spray solution (Anonym, 1975).
