Gao, Changlu; Zhang, Suobo; Gao, Lianxun; Ding, Mengxian published the artcile< Microwave-assisted synthesis of high-molecular-weight poly(ether imide)s by phase-transfer catalysis>, Synthetic Route of 118-45-6, the main research area is polyether polyimide polycondensation phase transfer catalysis polymerization microwave.
A facile and rapid polycondensation reaction of disodium bisphenol A with bis(chlorophthalimide)s was preformed with a domestic microwave oven in o-dichlorobenzene by phase-transfer catalysis. The polymerization reactions, in comparison with conventional heating polycondensation, proceeded rapidly and were completed within 25 min. The polymerizations gave the corresponding poly(ether imide)s with inherent viscosities of 0.55-0.92 dL g-1. The effects of various factors on the polymerization, such as the amount of the catalyst, the reaction time, and the microwave power were studied. The properties of the polymers were briefly characterized.
Journal of Applied Polymer Science published new progress about Glass transition temperature. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, Synthetic Route of 118-45-6.
