UV Cross‐Linkable Polymer Based on Triazine: Synthesis, Characterization and Crosslinking Studies

Abstract

Summary 3‐(4‐((4‐(4‐Acetylphenoxy)‐6‐((4‐nitrophenyl)amino)‐1,3,5‐triazin‐2‐yl)oxy)phenyl)‐1‐(2,4‐dichlorophenyl)prop‐2‐en‐1‐one (TAP) is synthesized using cynuric chloride, 2,4‐Dichloro‐1‐ene(4‐hydroxyphenyl)phenone,4‐nitroaniline and 4‐aminoacetophenone. 1‐(2,4‐dichlorophenyl)‐3‐(4‐((4‐(4‐(3‐(4‐hydroxyphenyl)acryloyl)phenoxy)‐6‐((4nitrophenyl)amino)‐1,3,5‐triazin‐2‐yl)oxy)phenyl)prop‐2‐en‐1‐one (TCC) is synthesized using TAP and 4‐hydroxybenzaldehyde. 4‐(3‐(4‐((4‐(4‐(3‐(2,4‐dichlorophenyl)‐3‐oxoprop‐1‐en‐1‐yl)phenoxy)‐6‐((4‐nitrophenyl)amino)‐1,3,5‐triazin‐2‐yl)oxy)phenyl)‐3‐oxoprop‐1‐en‐1‐yl)phenyl acrylate (TCP) is synthesized using TCC and acryloyl chloride. Copolymers of the TCP are prepared using vinyl acetate, styrene, and acrylamide are carried out by solution polymerization technique by using benzoyl peroxide (BPO) under a nitrogen atmosphere. Monomer and polymers are characterized by using IR and NMR techniques. The photocrosslinking property of the polymers was done by using the UV absorption spectroscopic technique. The rate of photocrosslinking was enhanced compared to that of the homopolymers, when the TCP was copolymerized with the VA, AM and S. Thermal stability and molecular weights (Mw and Mn) are determined for the polymer samples and molecular weights of the polymers are found to be around 10000 g/mol.

Acrylate polymers of triazine containing chalcone moiety: Synthesis, characterization, reactivity ratio and photocrosslinking studies

“…These types of polymer have been crosslinked easily by the irradiation of UV light and used as printing inks, photoresist plates, coating materials, 1 liquid crystals, 2 tissue engineering, 3 biosensors, 4 UV-curing adhesives, 5 hole transporting materials in organic light emitting diodes 6 and optical anisotropy. 7 The polymers containing photosensitive moiety such as cinnamate, 8 chalcone, 9 stilbene 10 maleimide and anthracene 11 easily go through photo crosslinking upon irradiation . The rate of photocrosslinking of acrylate polymers was fast under mild conditions and used in several applications.…”
