摘要： Disclosed are methods of decreasing the concentration of a metal in a monomer composition including a bis(benzoyl)benzene, bis(benzoyl)benzene monomer compositions having a low total metal concentration, di-ketone polymers made from low metal bis(benzoyl)benzene monomers, and polymer compositions and shaped articles including the di-ketone polymers. It was surprisingly found that di-ketone polymers made by nucleophilic substitution of low metal bis(benzoyl)benzene monomers exhibit greater crystallinity, as compared with di-ketone polymers made with conventional monomers.

摘要： A method for converting vanillin to bis(cyanate) ester monomers, comprising treating vanillin with a reductive coupling agent to form at least one olefin. The olefin or olefins are treated with hydrogen and a metal catalyst to hydrogenate said olefin. The hydrogenated olefin or olefins are treated with at least one cyanogen halide and a base in an organic solvent to afford at least one olefin monomer. The olefin monomer or monomers are purified by recrystallization or precipitation from an organic solvent.

摘要： A polyarylate resin is represented by general formula (1) shown below. In general formula (1), R1 represents a hydrogen atom or methyl group. R2 and R3 each represent a hydrogen atom or an alkyl group having a carbon number of at least 1 and no greater than 4. R2 and R3 are not the same as one another. When R1 represents a hydrogen atom, R2 and R3 are not bonded to one another. When R1 represents a methyl group, R2 and R3 are optionally bonded to one another to form a ring. r and s each represent a number greater than or equal to 0 and less than or equal to 49. t and u each represent a number greater than or equal to 1 and less than or equal to 50. r+s+t+u=100. r+t=s+u.
