Gained resin is the high good resin of colorless and transparent property, and refractive index (ne) is 1.665, and Abbe number (ve) is 31,
Heat resistance is 90 DEG C, evaluation result is shown in table 1.
Table 1
A-1:2,5 (6)-bis- (isocyanate group) two ring-[2.2.1]-heptane
A-2: hexamethylene diisocyanate
A-3: pentamethylene isocyanates
A-4: m-xylylene diisocyanate
B-1:2,4,6- tri-thiol methyl-1,3,5- trithiane
B-2:2,5- bis- (thiopurine methyltransferase) -1,4- dithiane
B-3:4- mercapto methyl -1,8- dimercapto -3,6- dithia octane
B-4: pentaerythrite (3-thiopropionate)
B-5:2,4,6- tri-thiol ethyl -1,3,5- trithiane
B-6: the mixture trithiane that formula III, formula IV and formula V form
C-1: triethylene glycol
C-2: ethylene glycol
C-3: glycerol
C-4: mercaptoethanol
As can be seen from the above results, in Examples 1 to 4, using alicyclic isocyanate and combination, there are three mercapto alkane
The polymerizable composition, polymerizable composition of the mercaptan combination of the trithiane ring structure of base, the resin being formed by curing have high refractive power number and Gao Abei
Value, and have fabulous heat resistance and intensity.And in comparative example 1~4, although Abbe number, heat resistance and intensity difference can be obtained
Few material, but index of refraction is much smaller than the resin in embodiment.Therefore, the cured resin of polymerizable composition, polymerizable composition of the invention is special
It is not suitable as the material of high dioptrics product, such as before having wide application in fields such as eyeglass, camera guns
Scape.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
