  • Is poly (acrylic acid-co-polyacrylamide) a hydrophilic copolymer?
  • Poly (acrylic acid- co -polyacrylamide) is a copolymer that possesses hydrophilic properties with a large number of polar groups [ 11 ]. J. Zhu et al. successfully prepared poly (acrylic acid- co -polyacrylamide)-based superabsorbent materials through the graft copolymerization of okara with acrylic acid and acrylamide [ 12 ].
  • What is acrylic acid - co -polyacrylamide?
  • They are composed of a three-dimensional polymeric network structure that can absorb and hold water and nutrients during the growth period. Poly (acrylic acid- co -polyacrylamide) is a copolymer that possesses hydrophilic properties with a large number of polar groups [ 11 ].
  • What is the corrosion rate of polyacrylamide copolymers?
  • We used a conventional oil displace- ment agent partially hydrolyzed polyacrylamide (HPAM) as the control group. Table2 lists the corrosion rate ( V) and in- hibition efficiency (IE) of the copolymers. Steel rods have a corrosion rate of 7.8538mgcm −2h−1without HPAM, and this rate decreases to 2.0216mgcm−2h in the pres- ence of 6.0g/L HPAM.
  • Which amide group is hydrolyzed in polyacrylamide?
  • The functional amide group in polyacrylamide is hydrolyzed at 80–90°C [ 4 ]. The polymer solution must be stable in harsh conditions of salinity and temperature. Acrylamide-based polymers suffer from some deficiencies such as their rapid hydrolysis, facile thermal degradation, and undesirable properties.
