Fig. 2. (A) MALDI spiralTOF-MS high resolution mass spectrum of a PVP sample in contact with an aqueous bleach solution at pH 11 for 6 days and (B) the associated KMD plot using VP as the base unit (black dots: aged sample; red dots: pristine sample). The structure of the poly(vinyl pyrrolidone-co-vinyl succinimide) copolymer formed upon ageing (noted P(VP-co-VSI) is depicted in inset of (A)).
