PURPOSE: To obtain the title copolymer composition improved in heat resistance, low-temperature resistance and water resistance, by mixing a specified chlorosulfonated ethylene/α-olefin copolymer with a hydrotalcite, a thiuram, a maleimide and a dithiocarbamate. n CONSTITUTION: 100 pts.wt. chlorosulfonated ethylene/α-olefin copolymer of a chlorine content of 25W32wt.%, a sulfur content of 0.3W2.5wt.% and an ethylene to α-olefin ratio of 98/2W60/40 is mixed with 10W35 pts.wt. hydrotalcite, 0.5W5 pts.wt. thiuram (e.g., dipentamethylenethiuram), 0.5W5 pts.wt. maleimide (e.g., N,N'-m-phenylenedimaleimide), and 0.2W4 pts.wt. dithiocarbamate (e.g., nickel dibutyldithiocarbamate). n COPYRIGHT: (C)1989,JPO&Japio |
