| the new peak at δ 3.65 ppm was correlated with the methylene proton of p-carbon atom relative to the carbonyl group in PCL. It indicates that the PCL free radical formed by the hydrogen abstraction of the α-carbon atom relative to the carbonyl group in PCL by the action of the homolytic scission of organic peroxide will attack the double bond in the methacrylate unit。 It is well known that free radicals from the thermal homolysis of BPOs can be thought of as having nucleophilic properties , and they can abstract the hydrogen at the α-carbon atom relative to the carbonyl of PCL, leading to the stabilization of the resulting radical by forming conjugation with the carbonyl group. |
