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

Summary3‐(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.
