PURPOSE:To provide the subject composition which is excellent not only in moldability but also in properties such as impact and weather resistances. CONSTITUTION:100 pts.wt. vinyl chloride resin is blended with 3-20 pts.wt. chlorinated polyethylene (heat of crystal fusion by DSC: 0.5cal/g or less, and chlorine content: 20-50wt.%) obtained by chlorinating at 100-140 deg.C a polyethylene produced by polymerizing a high molecular weight component (a) of HLMFR of 0.01 l 15g/10min in the first step and then polymerizing a low molecular weight component (b) of MFR of 30-500g/10min in the second step in a ratio of the component (a) to the component (b) of 40:60 to 60:40. |
