Unfortunately, the ratio between the two monomers is not determined for this product on a lot-to-lot basis. However, historical data indicates a mixture of approximately 83 wt% 1-vinylpyrrolidinone and 17 wt% 2-dimethyl-aminoethyl methacrylate.

How many repeating units are there in this copolymer?
1 answer-
Approximately 83% 1-vinylpyrrolidinone and approximately 17% 2-dimethyl-aminoethyl methacrylate. Since the average Mw of 190888 is less than 1,000,000, theoretically there should be 830,000 of 1-vinylpyrrolidinone and 170,000 of 2-dimethyl-aminoethyl methacrylate. The Mw of each 1-vinylpyrrolidinone and 2-dimethyl-aminoethyl methacrylate unit is 111.144 and 157.21, respectively. Therefore, the repeating unit can be calculated as 830,000/111.144 ≈ 7468 and 170,000/157.21 ≈ 1081, respectively.
