| Résumé : |
Liquid crystalline polymers are polymers having a partially ordered state of the molecules. The orientation of the molecules along the flow direction is responsible for their lower viscosities, making them suitable for high solid coatings. Such polymers also exhibit a combination of excellent hardness and flexibility. The methods of synthesis of various types of resins such as acrylic, alkyd, polyester and epoxy has been reviewed along with the different techniques for their characterization. Advantages of liquid crystalline polymers over their amorphous counterparts has been discussed. Guidelines have been provided for formulating liquid crystalline acrylic copolymers for both baking as well as nonbaking applications. |
