摘要： PURPOSE:To produce a solvent-soluble low-molecular weight chlorinated polyolefin without using any organohalogen compound solvent. CONSTITUTION:A polyolefin having an average mol.wt. of 800-12,000 and a melt viscosity at 170 deg.C of 4,000 cP or lower is dispersed into an aqueous medium at a temp. higher than the melting point of the polyolefin by at least 5 deg.C, and the dispersed polyolefin melt is chlorinated until the combined chlorine content reaches 55-63wt.%. The chlorinated polyolefin is then reduced into smaller particles at a temp. not above the melting point, during which chlorination may be further conducted to a combined chlorine content of 60-72wt.%. By thus conducting the high-temp. chlorination in an aqueous medium and performing the particle reduction during the chlorination, a homogeneously chlorinated polyolefin excellent in solvent solubility is obtained.

摘要： PURPOSE:To provide wear resistance, flection resistance, and resistance to wrinkles, and to obtain a rigid fixation surface which has good surface glossiness and superior contamination resistance by carrying out a heat treatment at 160-250 deg.C for 5-30sec after forming an image on the surface of a body to be printed when a copy is taken by using toner. CONSTITUTION:For example, a normal constant-temperature heater, a heat roll, or infrared-ray heater with a reflecting plate is provided as a fixation processing means and copied printed matter is passed through a heating atmosphere. This method is applicable similarly to a polyethylene chloride sheet, sheet containing polyethylene chloride, or specified copying form and a sufficiently stable print image is obtained. Then the fixation processing temperature is 160-250 deg.C and the time is short or 5-30sec. In general, the time is preferably 5-20sec almost is 180 deg.C. Consequently, there is not the possibility of the contamination of a print part due to the sticking of other printed matter, not to mention the bleeding and desorption of a copy image, and the stable printed matter which can be stored permanently is obtained.
