The invention relates to new copolymers comprising a special phosphate functional monomer, and to uses thereof for example in coatings. The new copolymers can impart improved scrub resistance to said coatings.

Polymer and use thereof

Dispersing agents for solid plant-protection agrochemicals, for example pesticidal dispersible granules, comprise (a) at least one alkali or alkaline earth metal or ammonium lignosulfonate, intimately admixed with (b) at least one optionally sulfated, ethoxylated or ethoxylated-propoxylated di- or tri(1-phenylethyl)phenol.

Lignosulfonate/ethoxylated poly(1-phenylethyl)phenol dispersing agents

A surface active agent formed by a polyoxethylenated and polyoxypropylenated di and/or tri (1-phenyl ethyl) phenol with 16 to 35 statistically distributed recurrent oxyalkylenated units. The ratio between the number of recurrent oxyethylenated units and the number of recurrent oxypropylenated units ranges from 75/25 to 90/10. The surface active agent is prepared by means of the reaction of a di and/or tri (1-phenyl ethyl) phenol and a mixture of monoethylene glycol and monopropylene glycol with a monoethylene giycol/monopropyleneglycol molar ratio ranging from 75/25 to 90/10. The surface active agent can be used for producing concentrated emulsifiable solutions of active materials, in particular phytosanitary materials.
