Method for producing polymers that are predominantly formed from vinyl formamide |
| abstract |
The invention relates to a method for producing polymers that are predominantly formed from vinyl formamide and that contain a small amount of residual vinyl formamide monomers. Said method comprises the radical polymerisation of: (a) 49.9 - 99.9 wt. % N-vinyl formamide; (b) 0 - 50 wt. % of one or more radically polymerisable monomers; (c) 0.1 - 5 wt. % of at least one monomer from the group containing N-vinyl pyrrolidone, N-vinyl-N-methyl-acetamide, N-vinyl caprolactam and N-vinyl piperidone, whereby the monomer (c) is only added for the polymerisation when the fraction of monomer (a) that has not yet been polymerised is < 5 wt. %. |
