油性は改良されるものの耐寒性が悪化するためである。The mixing ratio of the α-olefin copolymer and the ethylene copolymer in the present invention is 99% of the α-olefin copolymer
% by weight or less and 50% by weight or more, the ethylene copolymer is 1% by weight or more and 50% by weight or less, preferably α-olefin copolymer 9 from the balance of oil resistance and cold resistance.
The ethylene copolymer is preferably 10% by weight or more and 50% by weight or less relative to 50% by weight or less of 0% by weight or less. The reason why the ethylene copolymer content is 50% by weight or less is that if it exceeds this amount, the oil resistance will be improved, but the cold resistance will deteriorate.
