PRODUCTION PROCEDURE OF COPOLYMER POLYCARBONATES. |
| abstract |
A METHOD FOR PREPARING COPOLYMERIC POLYCARBONATES IS PRESENTED, THIS METHOD IS CHARACTERIZED BY INDUCING POLYCONDENSATION IN A MELTED STATE OF A COMPOUND OF AROMATIC DIHYDROXIDE CONTAINING A QUANTITY OF 2 AND 90 MOL% OF HYDROQUIN-HYDROQUINONE, HIDROQUIN AND HIDROQUIN-AQUINES. PRESENCE OF A CATALYST THAT INCLUDES ALCALI METAL COMPOUNDS AND / OR ALCALINE EARTH METAL COMPOUNDS IN A QUANTITY OF BETWEEN 1 X 10 RAISED TO LESS 8 AND 5 X 10 MOLES PER MOL OF THE TOTAL AMOUNT OF DIHIDX COMPOUND AROMATIC. |
