DSC analysis of the composites based on modified silica and 2,7-NAF.DM. This represents changes in the heat capacity of materials numbered as in Table 1. 3 The mechanical mixture of the vinylated silica with poly2,7-NAF.DM. The silica/polymer ratio was 2:1. The mechanical mixture of vinylated silica with polymer was obtained in a micro ball mill. 4 The silica with chemisorbed polymeric layer obtained via in situ grafted polymerization of the monomer 2,7-NAF.DM on the vinylated silica surface. The silica/polymer ratio in the composite was 2:1 (sample 4 in Table 1)
