Title:
PRODUCTION OF CHLORINATED POLYOLEFIN
Document Type and Number:
Japanese Patent JP2725483
Kind Code:
B2
Abstract:
PURPOSE: To produce a solvent-soluble low-molecular-weight chlorinated polyolefin without using any halogenated solvent.
CONSTITUTION: A polyolefin of an average molecular weight of 800-12000 and a melt viscosity of 4000cP or above at 170°C is melted at a temperature at least 5°C higher than the melting point in an aqueous medium and chlorinated. This process is advantageous in an environmental pollution problem because no organic solvent is used, and can provide a polyolefin of a high chlorine content by performing uniform chlorination even in an aqueous medium.
