反応手順
As shown in Table 1, 1,5,7-triazabicyclo[4.4.0]dec-5-ene (pH 14.2), 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (pH=14.1), 1-n-butylguanidine (pH=14.0), 1,2-dimethyl-1,4,5,6-tetrahydropyrimidine (pH=13.6) and 1-n-butylbiguanide (pH=13.4) each used as a silanol condensation catalyst gave good curability data (Examples 1 to 6). On the contrary, the use of DBU (pH=13.3), DBN (pH=13.1) and 1,3-diphenylguanidine (pH=11.7) resulted in inferior curability (Comparative Examples 1 to 4).
