Hydrosoluble copolymers of acrylamide‐(2‐acrylamido‐2‐methylpropanesulfonic acid). Synthesis and characterization by spectroscopy and viscometry

Abstract

Hydrosoluble copolymers containing sulfonic acid groups incorporated into a macromolecule were synthesized. The group of polymers studied was obtained by free radical solution polymerization, using potassium persulfate as an initiator. The copolymerization of the monomers 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and acrylamide (AA) was carried out at different pH values of the reaction medium of the monomer mix. The copolymers were characterized by proton nuclear magnetic resonance spectroscopy ( 1 H NMR) and Fourier transform infrared spectroscopy (FTIR). The viscosity behavior of the copolymers in NaCl solution showed a dependency on the pH of the reaction medium, with higher pH leading to lower viscosities. The acidic conditions of this medium affect the initiator decomposition rate, which is a probable cause of the viscosity variation, and the extent of decomposition increases with increasing pH.

Synthesis and Characterization of Canola Oil Alkyd Resins Based on Novel Acrylic Monomer (ATBS)

“…The weak absorption band at 1,180 cm -1 can be attributed to SO 2 stretching vibrations, which also confirms the grafting of ATBS onto the alkyd resin. It is worth noting that the effectiveness of the reaction between the monomers can be confirmed by the absence of the characteristic band of vinyl monomers, due to C=C at 978 cm -1 [10,11].…”

“…It is a relatively strong acid that has broad applications, which include packaging films, foam stabilizers, photographic materials and water absorbents. The shielding effect produced from the unique geminal dimethyl structure of ATBS offers excellent hydrolytic stability to newly synthesized polymer resins [9][10][11][12][13]. Figure 1 illustrates the structure of ATBS, and Table 1 lists its technical parameters.…”

“…The newly synthesized styrenated COA was further modified by partial and complete replacement of styrene with different weight ratios of the novel anionic acrylic monomer acrylamido tertiary butane sulfonic acid (ATBS). The acrylic monomers, [9,10] introduced onto the backbone of the alkyd resin, improved coating properties such as weatherability, chemical resistance and hardness. Therefore, they are the most attractive polymers to be incorporated onto the backbone of alkyd resins.…”

Preparation of scale inhibitor by using the waste of refined 2‐acrylamido‐2‐methylpropane sulfonic acid

“…AMPS has attracted much research interests including synthetic fiber, petroleum industry, water treatment, paper making, and coating because of its thermal and antihydrolytic stability. The sulfonic acidic monomer AMPS has been used to synthesize various copolymers with conventional monomers, such as acrylic acid (AA), acrylamide (AM), etc [1][2][3]. As reported, polyepoxysuccinic acid (MA-AMPS) and the mixture of MA-AMPS and imidazoline all have good scale inhibiting ability to CaCO 3 and CaSO 4 in oilfields [4].…”
