研究了炭黑表面引入氯甲基引发2-恶唑啉开环聚合的机理。通过炭黑与3，3 ′-二氯甲基过氧化苯甲酰在四氯化碳中的反应，在表面引入氯甲基基团。在聚合过程中，基于聚合物从表面的增长，从炭黑接枝聚OZZ：接枝率随着转化率的增加而增加，达到40- 60%。通过加入碘化钾加速聚合。聚OXZ接枝炭黑在疏水性和亲水性溶剂中产生稳定的胶体分散体。
The ring-opening polymerization of 2-oxazolines (OXZs) was found to be initiated by chloromethyl groups introduced onto carbon black surface. The introduction of chloromethyl groups onto the surface was achieved by the reaction of carbon black with 3,3′-bischloromethylbenzoyl peroxide in carbon tetrachloride. During the polymerization, poly-OXZs were grafted from carbon black based on the propagation of the polymers from the surface: percentage of grafting increased with an increase of conversion and reached 40–60%. The polymerization was accelerated by the addition of potassium iodide. Poly-OXZ-grafted carbon black produced stable colloidal dispersions in both hydrophobic and hydrophilic solvents.
