<P>PROBLEM TO BE SOLVED: To provide a chlorosulfonated polyolefin composition having good viscosity characteristics and also excellent cold resistance. <P>SOLUTION: The chlorosulfonated polyolefin composition includes 2.0 pts.wt. or less of 1,1,2-trichloroethane relative to 100 pts.wt. of chlorosulfonated polyolefin. The Mooney viscosity M of the composition is 30-140 when measured using L form rotor and in conditions of 100°C according to JIS-K 6300 (2001 version). Also, the solution viscosity μ (mPa s) of the toluene solution in which the composition is 10 wt.% is within the range represented by the following formula (1) or (2). Formula (1): 9×M-220≥μ (mPa s) when 30≤M<80. Formula (2): 25×M-1500≥μ (mPa s) when 80≤M≤140. <P>COPYRIGHT: (C)2012,JPO&INPIT |
