I am working on NiPam Polymerization and I am unsure of the necessary amount of ammonium persulfate and TEMED necessary in the polymerization process. I am using water as the solvent and the reaction medium with no other monomer in the reaction.
Other methods are known for oxygen elimination in polymerization such as nitrogen pumping, but due to safety concerns in the lab, I am not allowed to do this.
My goal is to create 20 milliliters of the polymer which should be used to create a flexible solid. The polymer should be able to cast into a sheet where the mechanical composition values such as Young's Modulus will be tested for. Currently we are unable to find the necessary amounts of solvents, NiPam powder, ammonium persulfate and TEMED required in the polymerization process.
We will also attempt to create a second polymer where NiPam is cross linked with Bis. Is the procedure the same for NiPam and Bis copolymerization and what ratio of Bis to NiPam is required for copolymerization?
Dear Ani Reddy, the attached file and the following RG link provide interesting information.
There is another technique which allow the elimination of O2, its name is freeze-thaw cycling. My Regards

Dear Ani,
I am using 0.5 to 1% APS for polymerization of different monomers. What is NiPam &TEMED? May you explain me pl.
Thanks
Dear Syed Naqvi, they are respectively, N-isopropylacrylamide and N, N, N', N'-tetramethylethylenediamine. My Regards
