Silane‐Functionalized Organic Macrocyclic Compounds‐Modified UVCurable Polyurethane Coatings: Synthesisand Properties

Three-dimensional polymer based porous calix[4]resorcinarene has many applications due to its special properties. The special structure of this polymer and having hydroxyl groups in it can provide the necessary conditions for making derivatives with other functional groups so that we can prepare other compounds with other applications. To create functional groups and modify the surface of the polymer, silane coupling agent can be a good option to create new properties and effective applications in the porous surfaces of polymer calix[4]resorcinarene. This research intends to provide a simple method for the use of poly(calix[4]resorcinarene) in ultra violet curable organic coatings. For this purpose, first the poly(calix[4]resorcinarene) was synthesized and then, by surface modification, double carbon-carbon bonds were created on it so that we could use it in radiant coatings. Then, after characterizing the synthesized materials, the structure and properties have been studied. The results confirmed the structure of the synthesized materials. Surface modification improved the distribution of particles in the polymer matrix and provided better coatings also thermal stability of urethane acrylate resin increased.
