The use of a polymeric catalyst, rather than a conventional monomeric (inorganic or organic) acid catalyst, has a non-deleterious effect on the aging behavior and offers potential for control of rheological properties (spinnability, coatability, etc.) of the hybrid materials.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/95/166/053/0.pdf7392189501/12502/159516/111516/104516/112C03C14/00C03C2214/12C03C2214/32C04B35/624C08G77/08C08G77/50C08G77/585316695
