Description:
The invention discloses a multifunctional papermaking chemical additive which is an acrylamide polymer with viscosity average molecular weight of 500,000-2,000,000, wherein the acrylamide polymer is alinear random copolymer formed by structural units shown by formulas I, II and III. The multifunctional papermaking chemical additive is prepared from the raw materials acrylamide, dimethyl diallyl ammonium chloride and methyl acrylate and by performing solution polymerization for 2-4h at 60-80 DEG C. The multifunctional papermaking chemical additive is used as a chemical additive in the papermaking technology. Compared with the prior art, the multifunctional papermaking chemical additive disclosed by the invention has the following beneficial effects: paper strength can be improved while resin sticky matters in papermaking production can be removed; moreover, a situation that a single functional chemical product only can solve a single problem in papermaking before is changed, mutual influence of different paper
