SMALL PARTICLE SIZE HYPOPHOSPHITE TELOMERS OF UNSATURATED CARBOXYLIC ACIDS
The present invention provides compositions comprising particles or agglomerates of one or more phosphorus oxide telomer or cotelomer ((co)telomer) of one or more unsaturated carboxylic acids or anhydrides having a mean average particle size of from 2 μm to 1 mm, preferably from 5 to 500 μm, prefera...

| description | The present invention provides compositions comprising particles or agglomerates of one or more phosphorus oxide telomer or cotelomer ((co)telomer) of one or more unsaturated carboxylic acids or anhydrides having a mean average particle size of from 2 μm to 1 mm, preferably from 5 to 500 μm, preferably, comprising at least one carboxylic acid anhydride group. In addition, the present invention provides methods comprising aqueous solution addition polymerizing a monomer mixture of one or more unsaturated carboxylic acid in the presence of a phosphorus oxide acid or salt compound, drying the resulting copolymer at a temperature of from 120 to 230° C. and reducing its particle size to make a phosphorus oxide (co)telomer particle or agglomerate; the methods may further comprise reacting the (co)telomer particle or agglomerate with one or more polyether polyol, alkyl polyether polyol, polyether amine or alkyl polyether amine, with heating, to form a comb polymer useful, e.g. as a superplasticizer or dispersant. |
