Process for altering the properties of high molecular weight halogen containing substances

Claim 1

A PROCESS FOR ALTERING THE PROPERTIES OF ORGANIC HIGH MOLECULAR WEIGHT POLYMERIC SUBSTANCES, THE MOLECULES OF WHICH UNINTERRUPTED POSSESS CARBON CHAINS WHICH PREDOMINATLY ARE LINEAR AND WHICH CARRY CHLORINE ATOMS DIRECTLY ON CARBON ATOMS OF SUCH LINEAR CHAINS, WHICH COMPRISES HEATING SUCH POLYMERIC SUBSTANCES IN CONTACT WITH 0.01-10% BY WEIGHT BASED ON THE POLYMERIC SUBSTANCES OF A MONOMERIC N,N''-DIMETHYLOL COMPUND OF A POLYAMINE SELECTED FROM THE GROUP CONSISTING OF PRIMARY AND SECONDARY ALKYLENE-, ARALKYLENE-, ARYLENE-, ALKYL ARYLPOLYAMINES AND SUCH PRIMARY AND SECONDARY POLYAMINES WHICH ARE AMINO SUBSTITUTED ALKYLENE-, ARYLENE-, ARALKYLENE-, ALKYLARAYLENE-HYDROCARBONS CARRYING AT LEAST ONE FURTHER SUBSTITUENT ON SUCH HYDROCARBON RADICAL SELECTED FROM THE GROUP CONSISTING OF OXALKYL GROUPS, HYDROXYL GROUPS AND HETEROCYCLIC GROUPS AT A TEMPERATURE OF AT LEAST ABOUT 80*C. TO EFFECT CROSS-LINKING OF SAID POLYMERIC SUSTANCES WITH SAID N,N''-DIMETHYLOL COMPOUND AS CROSSLINKING AGENT.
