제목 Ball Milling Prompted Atom Transfer Radical Polymerization in the Solid-State
초록 Poly(2-vinylnaphthalene) was synthesized in the solid-state by ball milling a mixture of the corresponding monomer, a Cu-based catalyst, and an activated haloalkane as the polymerization initiator and the reaction was optimized. The reaction was monitored and found to be linear correlations between monomer conversion and polymer molecular weight. While the polymer molecular weight was effectively tuned by changing the initial monomer-to-initiator ratio, the experimentally measured values were found to be lower than their theoretical values. The difference was attributed to premature mechanical decomposition and modeled to accurately account for the decrement. Random copolymers of two monomers with orthogonal solubilities were also synthesized in the solid-state. Collectively, the data indicated that the solid-state polymerization reaction is controlled, follows a mechanism similar to that described for solution-state atom transfer radical polymerizations.
