•The influence of molar composition of the monomer to the copolymer was investigated.•The flocculating activity of resulted copolymer was investigated.•The flocculation of several suspensions was tested using homo and copolymer.•The optimal dosage of copolymer for flocculation was found.•The influence of polymer dose on the zeta potential of particles was investigated.
Radical copolymerization of N,N-dimethyl-N,N-diallylammonium chloride (DMDAAC) with N,N-dimethylacrylamide (DMAA) has been investigated by FT-IR, 1H NMR spectroscopies, conductometric and turbidimetric titration methods. Flocculation of bentonite suspensions, pig, chicken and cow manure slurries were investigated using the copolymer P(DMDAAC-DMAA) with various compositions and homopolymer P(DMDAAC) by turbidimetric method and the zeta potentials of each samples were tested. The results indicated that copolymer P(DMDAAC-DMAA) (with molar composition 70:30) has the best flocculating ability compared to the other compositions and homopolymer P(DMDAAC). Compared to four suspensions pig manure was found to be more difficult to settle down.
