High Efficient Grafting Polymerization of Styrene on Surface of NBR Latex and Physical Properties of NBR/NBR-g-PSt Composite [PDF]
The grafting polymerization of styrene on the surface of commercial available vulcanized acrylonitrile butadiene rubber (NBR) latex was initiated by the heat decomposing cleavage of dormant groups of semipinacol (SP) immobilized firstly under UV irradiation. Extremely high grafting efficiency in the range from about 90% to nearly 100% could be achieved.
