摘要： Bis(haloximino)acetone derivatives are prepared by a process comprising reacting acetone with an nitrosyl halide in an inert solvent, at a temperature of from -50* to 25*C. A typical embodiment is bis(chloroximino)acetone. These compounds are useful as cross-linking agents, chain-extending and/or capping agents for unsaturated polymers.

摘要： AROMATIC CARBONYL HYDROXAMOYL CHLORIDES ARE PREPARED BY A PROCESS COMPRISING REACTING AN AROMATIC ACETYL COMPOUND WITH NITROSY CHLORIDE IN AN INERT SOLVENT, AT A TEMPERATURE OF FROM -5 TO 25*C. IT IS OF CRITICAL IMPORTANCE THAT THE NITROSYL CHLORIDE BE FREE OF CONTAMINANTS WHICH INTERFERE WITH SAID REACTION. THESE COMPOUNDS ARE USEFUL AS CROSSLINKING, CHAIN EXTENDING AND/OR CAPPING AGENTS FOR UNSATURATED POLYMERS OR POLYMERS CONTAINING MERCAPTAN GROUPS.
