The present invention provides compositions comprising particles or agglomerates of one or more telomere or ((co) telomere) telomere or one or more methacrylic acids or anhydrides having an average average particle size of from 2 µm to 1 mm, preferably of 5 a. 500 µm In addition, the present invention provides methods comprising adding the aqueous solution that polymerizes a monomeric mixture of one or more methacrylic acids in the presence of a heteroatom-containing compound, drying the resulting copolymer at a temperature of from 120 to 230 ° C and reducing its particle size to make a particle or agglomerate of (co) telomere; The methods may further comprise reacting the (co) telomere particle or agglomerate with one or more of polyether polyol, alkyl polyether polyol, polyether amine or alkyl polyether amine, with heating, to form a useful comb polymer, for example, as a super plasticizer or dispersant. |
