Abstract

The authors compared the efficiency of (meth)acrylic polymers containing  ammonium groups in the main chain or side fragments as modifying additives for the paper for corrugating. As carbon-chain polymer additives we used the copolymer of acrylamide and N,N-dimethylaminoethyl methacrylate hydrochloride (75:25, sample CP-1) and the  homopolymer of N,N-dimethylaminoethyl methacrylate quaternized with dimethyl sulfate (sample CP-2), obtained by radical polymerization. For the samples CP-1 and CP-2, the average molecular weight (MW) determined using the Mark-Houwink equation was 1980000 and 9570000 respectively. Products of stepwise polymerization of N,N-dimethy-laminoethylacrylate were used as heterochain polymer additives; their MWs were 10,100 for the sample GP-1 and 5,600 for the sample GP-2 (MWs were determined by the content of terminal vinyl groups). All the additives significantly improve strength properties of paper: bursting strength (BS), fracture strength (FS), flat crush resistance, ring crush resistance, and edgewise compression strength. The following parameters increased the most: BS (two times), FS (up to six times); water absorption reduced (up to two times). The effect of the cation charge and MW on the efficiency of the carbon-chain polymer additives was found in solutions with concentration up to 0.2 % of the weight (based on absolutely dry paper fibers), while in more concentrated solutions this effect was absent. For the ionenes GP-1 and GP-2, the optimal concentration range was 0.1–0.2 % of the weight. At higher concentrations, there was a sharp decrease in strength and water absorption properties of the paper. Due to higher water solubility and lower viscosity of pulp, the ionen additives GP-1 and GP-2 have a clear advantage. They need only 10 min to dissolve in the water at room temperature. The more high-molecular polymers CP-1 and CP-2 dissolve only upon being stirred for 3 hours or more at the temperature of 40–60 °C.
