Cross-linkable chlorinated aromatic polymers

Abstract

Abstract A CROSS-LINKABLE, SHAPEABLE POLYMERIC COMPOSITION COMPRISING THE GROUPS (-AR-)X AND (-A-AR''-A-)Y IN SUBSTANTIALLY ALTERNATING SEQUENCE AND A GROUP (-A-AR''-AH)Z CAPABLE OF CROSS-LINKING POLYMER CHAINS THROUGH THEIR -AR- MOIETIES, WHEREIN -A- IS -O- OR -S-, -AR- IS A DIVALENT PERCHLORINATED AROMATIC GROUP OF 10-24 AROMATIC CARBON ATOMS -AR''- IS A DIVALENT AROMATIC GROUP OF 6 TO 24 AROMATIC CARBON ATOMS, THE GROUPS BEING PRESENT IN AMOUNTS SUCH THAT Y+Z X IS IN THE RANGE OF 1.01 TO 1.6, THE POLYMER HAVING AN INHERENT VISCOSITY OF AT LEAST 0.2. A PROCESS OF PREPARING THE ABOVE DESCRIBED POLYMERS BY REACTING A COMPOUND OF THE FORMULA CL-ARCL WITH A 1.01 TO 1.0 MOLAR AMOUNT OF A COMPOUND OF THE FORMULA HA-AR''-AH AT FROM 25 TO 250*C. IN THE LIQUID PHASE AND PREFERABLY IN A SOLVENT FOR ONE OR BOTH OF THE MONOMERS.
