Abstract
PURPOSE: A linear, low-density polyethylene (abbreviated to LLDPE hereinafter) with specific physical properties is used as a starting material to produce a chlorinated polyethylene with good rubber properties.
CONSTITUTION: A powder of LLDPE with a melt index of less than 10, a density of 0.915W0.94, preferably 0.92W0.935, and particle sizes of preferably 100W200 microns, is suspended in an aqueous medium and the chlorination is started at a temperature about 5W15°C lower than the melting point of LLDPE. When the chlorine content of LLDPE exceeds 10wt%, the chlorination temperature is controlled to 100W130°C and the chlorination is continued, till the content becomes 20W45wt%.
EFFECT: When processed, the product can be kneaded with rolls of room temperature and the adhesion between resins is good.
