Abstract
A polytriazole copolymer may include substituted phenyls, substituted benzyls, or both substituted phenyls and substituted benzyls. The substituted phenyls and the substituted benzyls may be independently substituted with hydrogen, bromo, fluoro, chloro, iodo, hydroxy, methyl, trifluoromethyl, dimethylamino, tert-butyl, carboxyl, triphenylmethyl, tris(4-fluorophenyl)methyl, tris(4-methylphenyl)methyl, (4-hydroxyphenyl)diphenylmethyl, and difluoromethoxy groups. The polytriazole copolymer may have a degree of polymerization from 25 to 250.
Claims19
A polytriazole copolymer having a structure according to formula (I):
- where:
- R1 and R2 are independently selected from —C(CF3)2— and —O—;
- R3 and R4 are independently selected from substituted phenyls according to formula (a) and substituted benzyls according to formula (b):
- where:
- X1, X2, X3, X4, and X5 are independently selected from hydrogen, bromo, fluoro, chloro, iodo, hydroxy, methyl, trifluoromethyl, dimethylamino, tert-butyl, carboxyl, triphenylmethyl, tris(4-fluorophenyl)methyl, tris(4-methylphenyl)methyl, (4-hydroxyphenyl)diphenylmethyl, and difluoromethoxy, provided at least one of X1, X2, X3, X4, or X5 on each R3 and each R4 is not hydrogen;
- m and n represent monomer mole fractions in the polytriazole copolymer;
- 0<m<1;
- 0<n<1;
- m+n=1,
- provided that when R1 and R2 are identical, R3 and R4 are not identical, the polytriazole copolymer having a degree of polymerization from 25 to 250.
