PROCEDURE IN TWO STAGES TO PREPARE THERMOPLASTIC POLYCARBONATES. |
| abstract |
THE OBJECT OF THE PRESENT INVENTION IS A FUSION PROCEDURE IN TWO STAGES FOR THE SYNTHESIS OF THERMOPLASTIC POLYCARBONATES, WITHOUT SOLVENTS, WITH A FEW RAMIFICATIONS AND WITH A LOW CONTENT IN GROUPS OR TERMINALS. Ammonium or phosphonium catalysts are used in the first stage, and alkaline and alkaline earth catalysts in the second stage. |
