depending upon reaction conditions, the product may be a polyketone formed by addition polymerization of the ketene double bond.
随着反应条件的不同,产物可以是由烯酮的双键加成聚合得到的聚酮。
polyketone (stco) was prepared by the copolymerization of carbon monoxide and styrene catalyzed by a composite catalyst system- palladium acetate, 2,2' bipyrodine associated with a strong acid.
the organic fiber cord is formed of a polyketone fiber cord.
有机纤维帘线由聚酮纤维帘线构成。
the photodegradations of polyketone samples and blends of polyketones with polystyrene(ps) were studied. it shows that the higher molecular weight of polyketones is the better photodegradation rate.
