| titleOfInvention |
The water soluble hydroxyalkyl polymer obtained by anti-phase suspension or inverse emulsion polymerization method |
| abstract |
The present invention relates to a kind of bead or the water-soluble polymers of powder type; the polymer is characterized in that it has the brookfield viscosity greater than 100cps; and it is that the polymer is to obtain there are transfer agent by the anti-phase suspension of monomer or inverse emulsion polymerization, wherein the monomer less than 20mol% is by with formula H 2 C=CR 1 R 2 Hydroxyalkyl monomer composition, R 1 For hydrogen atom or methyl, R 2 To include at least one OH side group or at least one epoxy group and the heteroatomic alkyl of optional at least one N or O in hydrocarbon chain；R 2 Different from C (=O)-OH group. |
