摘要：
Cement mortars were modified with the soap-free cationic emulsion copolymer of vinylacetic acid (VAC) and methacyloy loxyethyl trimethylammonium chloride (DMC). The properties of the modified mortars were compared with those modified with polyvinyl acetate (PVAC). The results indicate that in comparison with the plain cement mortar, the bending strength of the mortars modified with the soap-free cationic emulsion copolymer of VAC/DMC[m(p)/m(c)=0.1] increases by 77%, and is better than that of the mortars modified with PVAC. The mechanism of the cement mortar modification by the VAC/DMC soap-free cationic emulsion copolymerization is discussed.
