<p>Water-soluble monomers and water-soluble polymers derived therefrom are disclosed. These materials can be used with other vinyl monomers to form water-soluble polymers which are reactive with cellulosic substrates to obtain drastically improved strength, particularly when applied in paper manufacture. The polymers contain at least two mole percent of a monomer represented by the chemical structure: < IMG > wherein R is -H, -CH3, or -C2H5; and A is 0, or N(R1); and B is CH2, CH2CH2O, ?CH2?n N(R1) (CH2?m, < IMG > ;and < IMG > ;and wherein R1 is -H, -CH3, -C2H5, (CH2CH2O)nH, or (B)qD, and wherein q is from 1-6, except when B contains nitrogen in which case q is always one; and wherein R2 is -H, -CH3, -C2H5, or (CH2CH2O)nH; and wherein R3 is < IMG > ; and wherein R4 and R5 may be the same or different and are, for each individual occurance, -H, -CH3, or -C2H5; and wherein æ is from the group Cl, Br, I, NO3, SO4 and the like; and whexein m ranges from 0-6; and wherein n is from 1-6.</p> |
