acrylamide-ran-methyl methacrylate copolymers synthesized

a series of well-defined acrylamide/methyl methacrylate random copolymers (pam-ran-pmma) were synthesized in this work. the polymerization reactions were carried out in n,n-dimethylformamide (dmf) at 25 °c using cu(0)/hexamethylenetetramine (hmta) and ccl4/hydrazine as the catalyst system and the initiator system, respectively. the number average molecular weights (mn) and the distribution of

a novel highly stretchable, adhesive and self-healing silk,a novel material system hydrogel was composed of silk fibroin powder (sfp) and polyacrylamide (pam). the dual-network structure hydrogel was prepared by a simple one-pot method of copolymerization. the sfppam hydrogels achieve high mechanical properties, which is superior to previous reported sfpam hydrogel.

similarly, block copolymerization of the pam-br macroinitiator (synthesized under the same recipe as described in table 2, m n,nmr 5.83 kda, and đ 1.15, figures s9 and s10) and 2-hydroxyethyl acrylamide (heaa) was performed with a ratio of [heaa] 0 /[pam-br] 0 of 100/1, with me 6 tren as the ligand and cu(0) wire and cu ii as catalysts in

optimized conditions for graft copolymerization of poly,the optimum concentration of initiator and nitric acid were 0.007 m and 0.2 m, respectively. the polyacrylamide (pam) homopolymer was removed from the graft copolymer by soxhlet extraction using distilled water. the pre-treatment rwf before the grafting procedure showed that grafting of acid-treated had a higher efficiency than alkali- treated

copolymerization polyacrylamide with nice quality

it was reported that polyacrylamide (pam) has good complexion ability with metal ions in solution (11). this is due to the fact that pam can form strong coordination bonds with heavy metal ions in solution. however, the good solubility of pam in water contributed to the poor ability of pam to adsorb heavy metal ions in real applica-

partially hydrolyzed polyacrylamide: enhanced oil recovery,polyacrylamide (hpam), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. it works by increasing the viscos-ity of the injected water, thus improving its mobility and oil recovery. however, during such enhanced oil recovery (eor) operations, it also produces a huge quantity of water alongside oil.
