| titleOfInvention | Vinylpyrrolidone (co) polymer |
| abstract | The present invention provides a vinyl pyrrolidone (co) polymer which, despite its low molecular weight, is excellent in color tone and thermal yellowing resistance. The vinyl pyrrolidone (co) polymer of the present invention is a vinyl pyrrolidone (co) polymer which has a Hazen value of not more than 30 in the form of a 5% aqueous solution and a K value of not more than 60, and is obtained by a process which includes the step of polymerizing a polymerizable monomer component with an azo compound initiator and / or an organic peroxide initiator, the polymerizable monomer component containing N-vinylpyrrolidone and the azo compound initiator having a through -C (CH¶3¶) ¶2¶ -N = NC (CH¶3¶) ¶2¶- has a chemical structure and the organic peroxide initiator is soluble in water or ethyl alcohol at 25 ° C. in an amount of not less than 3% by weight. |
