| Abstract: | Brands and dodge of chlorinated polyethylene rubbers（CM） and dosages of plasticizers on properties of PVC/CM thermoplastic elastomers were studied. Experiments results show that： （1） when the mass ratio of PVC to CM5236 is 100 ： 10, and the dosage of DOP is 80 parts, PVC/CM thermo- plastic elastomer can obtain the best mechanical property with tensile strength 12 MPa and elongation at break 400% - 500%, while its hardness maintaining about 65 （Shao A） ; （2） PVC with high polymerization degree can improve the tensile strength, elongation at break and low temperature re- sistance of PVC/CM thermoplastic elastomer, but excessive high polymerization degree can cause the increase of hardness of PVC/CM thermoplastic elastomer, so the polymerization degree of PVC should be controlled at 1 000 - 2 000; （3） with the increase of CM dosage, the low temperature re- sistance of PVC/CM thermoplastic elastomer becomes better; （4） the adding of small amount of powdered butadicne-acrylonitrilc rubber （P83） can increase the tensile strength and elongation at break of PVC/CM thermoplastic clastomcr, and improve its low temperature resistance. |
