“…From these figures it can be seen that with increase of monomer concentration, the polymerization conversion and rate also increased. We suggest this may be due to the formation of relatively high active centers which led to strong interactions between the radicals 40 …”

The kinetics of copolymerization is one of the key factors for optimization the process in large scale of production. Copolymerization of N, N‐dimethyl‐N,N‐diallyammonium chloride (DMDAAC) with N,N‐dimethyl acrylamide (DMAA) was studied by a dilatometer technique using ammonium persulfate ([NH4]2S2O8) as an initiator. The effect of the parameters (including molar ratio of DMDAAC to DMAA, concentrations of monomers [M] and initiator [I], and the temperature) on the polymerization rate was analyzed. From these analyses it was found that the polymerization rate (Rp) with the above variables can be represented as the following relationship: Rp∝ [M]2.63; Rp∝ [I]0.40 andRp∝[MDMDAAC:MDMAA]‐0,86.The negative order found in the relationship of the reaction rate and the monomer composition indicated that the DMDAAC concentration in the monomers composition conversely affected the polymerization rate. The overall activation energy for the polymerization rate was 39.56 kJ/mol in the temperature range between 40°C and 60°C. Based on the experimental results, the mechanism of polymerization is discussed in detail. Different thermal properties for DMDAAC and DMDAAC‐DMAA were observed by differential scanning calorimetry (DSC), and thermogravimetry (TG) analysis. Addition of DMAA to DMDAAC lowered the thermal stability relative to the home polymer of DMDAAC.

“…The precipitated copolymers were then dried under vacuum at 313 K until a constant weight was achieved. The composition of the copolymers was investigated using fourier‐transform infrared spectroscopy, hydrogen‐1 nuclear magnetic resonance and 13 C NMR spectroscopy, and conductometric titration (Abdiyev et al, ; Dauletov et al, ).…”

N,N‐diallyl‐N,N‐dimethylammonium chloride (DADMAC) and vinyl ether of monoethanolamine (VEMEA) copolymer P(DADMAC‐VEMEA) were synthesized using radical polymerization in water media using ammonium persulfate as an initiator. The synthesis of this copolymer was investigated over a wide composition range at low conversion levels. The viscosity of the copolymers was measured in aqueous 1 M NaCl. Flocculating action and antimicrobial activities of the copolymers P(DADMAC‐VEMEA) against microbacteria and sulfate‐reducing bacteria (SRB) were studied. Synthesized copolymers had flocculating effects and can be used to purify wastewater from particles of bentonite clays. Also, the copolymer with a molar composition [DADMAC]: [VEMEA] = (80÷20):(20÷80) retarded the population of both bacteria, Gram‐positive (Staphylococcus aureus) and Gram‐negative (Escherichia coli) in the diffusion zone. Furthermore, the copolymer with a molar composition [DADMAC]:[VEMEA] = (90÷10):(20÷80) had bactericidal properties against SRB. Minimum inhibitory concentration (MIC) of the copolymer varied from 0.01% to 0.1% depending on the molar composition of the copolymer.

“…As a result, the chain extension reaction rate increased, meanwhile, the chain termination rate in the polymerization system remained unchanged, so the polymerization rate increased. 16 The effect of monomer concentration on polymerization rate equation was indicated as: R pA / [M] 1.64 and R pV / [M] 1.57 , respectively. The reaction order with respect to the monomer had been found to be between 1.5 and 2.0.…”

The poly(3-methacryloylamido propyl trimethyl ammonium chloride) (PMAPTAC) was synthesized by radical polymerization in aqueous solution polymerization using ammonium persulfate (APS) and 2,2 0 -azobis(2-methylpropionamide) dihydrochloride (V50) as initiator, respectively. The kinetics of polymerization were examined by changing various monomer and initiator concentrations via the dilatometer method at a low conversion level. The results showed that the polymerization rate grew with increasing monomer, initiator concentrations, and temperatures. The activation energies of polymerization were E aA = 153.09 kJ/mol and E av = 144.76 kJ/mol. The overall polymerization rate equation for the PMAPTAC were R p = k[M A ] 1.64 [I A ] 0.71 and R p = k[M V ] 1.57 [I V ] 0.91 at the temperature of 45 C for APS and V50, respectively.Based on the experimental results, the effect on the polymerization rate of different initiators was discussed. The studies supplied the experimental basis of the kinetics for the reaction control of PMAPTAC production.
