Ultrasound Assisted Continuous Process for Making Polymer Blends and Copolymers
This invention relates to a process for making polymer blends and copolymers by ultrasonic treatment during or after mixing the polymers. In the process of the present invention, an unexpected phenomenon occurs. The process brings about enhancement of the mechanical properties when compared with identical blends not subjected to ultrasonic treatment. The ultrasonic treatment of the blends is believed to enhance intermolecular interaction and improve adhesion between dissimilar polymers and make chemical bonds between polymers that otherwise are incompatible or immiscible with each other.
