SYNTHESIS AND CHARACTERISTICS OF GRAFT COPOLYMERS OF POLY (BUTYL ACRYLATE) AND CELLULOSE WITH ULTRASONIC PROCESSING AS A MATERIAL FOR OIL ABSORPTION
Gao, Yuan - Zhou, Yitong - Zhang, Xiaoli - Zhang, Liping - Qu, Ping

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	A series of materials used for oil absorption based on cellulose fiber grafted with butyl acrylate (BuAc) have been prepared by radical polymerization under ultrasonic waves processing. Effects of ultrasonic dose for the maximum graft yield were considered. The dependency…
