NOVELTY – The set of solid e.g. polyvinyl alcohol comprises films of pure PVA containing incorporated S-nitrosothiols (0.001-25 per cent by weight relative to the PVA). Also claimed is a process for making the films. CLAIMED PROCESS – The process forms films of PVA and PVA-polyvinyl pyrrolidone containing S-nitrosothiols as donors of nitric acid. USE – In polymer chemistry.
