Synthesis, Adhesion Strength, Solubility and Photo Stabilization   Properties of Novel Polyethylene Based Copolymers

The synthesis of novel copolymer Synthesis of Acrylic acid-Co-polymer-Co-(N-allyl-amino benzothiazole) acrylic amide and / the synthesis of acrylonitrile copolymers was carried out in two main stages. Initially, aromatic amine derivatives were reacted with allyl chloride in the presence of dimethylformamide (DMF) to obtain the desired intermediates. These purified intermediates were then further treated with allyl chloride to produce the corresponding allyl-substituted compounds. Subsequently, copolymerization was achieved through a free radical process involving the reaction of N-allyl aromatic amine derivatives with acrylic acid, using AIBN as the radical initiator. The synthesized compounds (A1–A5) were characterized using Fourier Transform Infrared Spectroscopy (FT-IR), while the resulting copolymers (P1–P5) were analyzed by FT-IR, Proton Nuclear Magnetic Resonance (¹H NMR), Gel Permeation Chromatography (GPC), and Thermogravimetric Analysis (TGA).The prepared copolymers were incorporated into poly (vinyl chloride) (PVC) as additives in specific proportions, and the resulting composites were subjected to UV irradiation for 300 hours. The results indicated excellent photostabilization performance. The adhesion strength of the polymers was determined using the single-lap shear method. Additionally, solubility tests in various solvents showed that the polymers exhibited good solubility in selected media.
