Investigation of the Structure of Poly-（N-hydroxymethyl） -acrylamide-Resorcinol Aerogel with SAXS

Strural investigations of Poly-（N-hydroxymethyl）-acrylamide-resorcinol aerogel by SAXS are reported. The results illustrated that the edge of the aerogel particles is clear, which is according to the model of Porod. Special surface of the aerogel calculated with SAXS is almost same as that gotten from BET. The difference of structure between sol-gel and aerogel displays that the polymeric chains have some freedom in the network of the structure of both gels.
