| titleOfInvention | Manufacturing process for polycarbonate using BH4 P compounds |
| abstract | A melt transesterification process for the production of polycarbonate comprising: reacting a bis(aryl)carbonate with a dihydric phenol in the melt phase, in the presence of a transesterification catalyst comprising at least one heterocyclic borate salt of the formula (I) RPBH4, in which R is main or side chain of C1~C6 or R1R2N-R3.R1,R2,R3 are independent and C1~C4 alkyl. The catalyst(I) can singly be used or blended with boric acid or phenol antioxidant. |
