Synthesis
(1) Adjustment of mixed solution (a2)~(a5) According to the following formulation, mixed solution (a2)~(a5) was prepared.
Mixed solution (a2) (i) AEEp-1 76 parts by weight, (ii) MTBD 24 parts by weight, (iii) methyl isobutyl ketone (MIBK) 100 parts by weight, (iv) irgacure 907 4 parts.
Mixed solution (a3) (i) AEEp-1 79 parts by weight, (ii) PEMP 21 parts by weight, (iii) MIBK 100 parts by weight, (iv) irgacure 907 4 parts by weight.
Mixed solution (a4) (i) AEEp-1 78 parts by weight, (ii) DPMP 22 parts by weight, (iii) MIBK 100 parts by weight, (iv) Irgacure 907 4 parts by weight.
Mixed solution (a5) (i) AEEp-1 68 parts by weight,(ii) QE340 32 parts by weight, (iii) MIBK 100 parts by weight, (iv) Irgacure 907 4 parts by weight.
(2) Reaction of mixed solution (a2)~(a5), fluorine content, refractive index, compatibility and IR absorption measurement In a glass sample bottle each 5 ml, each mixed solution (a2)~(a5) 1 g was charged. The ultraviolet rays of intensity 5000 mJ/cm2U were irradiated with each mixture by using a high pressure mercury lamp from the top of the sample bottle without lid. Then, air dried at room temperature, MIBK was removed.
