Comparing poly(p-phenylene), poly(benzoyl-p-phenylene) is more easily synthesized and has more large molecular weight and is more easily soluble in common organic solvents. 2,5-Dichlorobenzophenone was synthesized from the reaction of 1,4-dichlorobenzene and benzoyl chloride in the presence of aluminium chloride. Poly(benzoyl-p-phenylene) was synthesized by the polymerization of 2,5-dichlorobenzophenone.??? The glass transition temperature of this polymer was 206 oC, and the decreased weight of the polymer was only 5% at 500 oC under nitrogen gas, so this polymer has excellent thermal stability. The copolymers were synthesized from the copolymerization of 2,5-dichlorobenzophenone (85%) and 1,3-dichlorobenzene (15%), the copolymerization of 2,5-dichlorobenzophenone (85%) and 1,4-dichlorobenzene (15%) respectively. These copolymers got poor thermal stability than poly(benzoyl-p-phenylene), but got better solubility and compatibility. These copolymer were characterized by NMR, IR, UV, GPC, DSC, TGA, and viscometer. And melting point and solubility were also measured. Using the synthesized polymer and copolymer, the coating on polycarbonate plate were tried to improve surface character by solvent casting method, and the blending with? polycarbonate were also tried to test the compatibility.
