Emulsification of hydrophobic organophosphorous compounds

A method for forming an emulsion comprising at least one polymeric surfactant, water and at least one hydrophobic organophosphorous compound selected from the group consisting of:

• wherein
• each R1 is independently a monovalent aryl, arylalkyl, or alkyl substituent containing up to 20 carbon atoms,
• each R3 is independently a monovalent aryl, arylalkyl, alkyl, hydrogen, phosphate ester, silyl, or phosphonate ester substituent containing up to 20 carbon atoms;
• each R2 is independently a divalent aryl, arylalkyl, or alkyl substituent containing up to 20 carbon atoms;
• R1, R3 and R2 each optionally include one or more heteroatoms in the substituents;
• and
• n is from 1 to 100;
• wherein
• each R1 is independently a monovalent aryl, arylalkyl, or alkyl substituent containing up to 20 carbon atoms,
• each R3 is independently a monovalent aryl, arylalkyl, alkyl, hydrogen, phosphate ester, silyl, or phosphonate ester substituent containing up to 20 carbon atoms;
• each R2 is independently a divalent aryl, arylalkyl, or alkyl substituent containing up to 20 carbon atoms;
• R1, R3 and R2 each optionally include one or more heteroatoms in the substituents;
• and
• n is from 1 to 100;
• and
• wherein
• R1 and R2 are independently monovalent aryl, arylalkyl, alkyl, hydrogen, phosphate ester, silyl, or phosphonate ester substituents containing up to 20 carbon atoms;
• each R3 and R4 are independently monovalent aryl, arylalkyl, or alkyl substituents containing up to 20 carbon atoms;
• R5 is a divalent aryl, arylalkyl, or alkyl substituent containing up to 20 carbon atoms;
• each R6 and R7 are independently divalent aryl, arylalkyl, or alkyl substituents containing up to 20 carbon atoms;
• R1, R2, R3, R4, R5, R6, and R7 each optionally include one or more heteroatoms in the substituents;
• m is from 1 to 100;
• and
• n is from 1 to 100,
• the method comprising:
• mixing the at least one polymeric surfactant and at least one hydrophobic organophosphorous compound to form a homogeneous mixture;
• and
• adding water to the homogeneous mixture while stirring the mixture until an oil-in-water emulsion is formed.
