At least the weight of the finishing null (i) copolymer in order to improve the resistance

摘要

Method of main inventing because acid content ratio at least raises the adhesion temperature of the pellet of ethylene based copolymer at 5 percentages by weight has with the step which makes the particular pellet the aqueous solution of the water soluble metal salt of the fatty acid contact which possesses the carbon atom under 12 and the step which makes that pellet dry. The ethylene based copolymer which is obtained has the adhesion temperature which is higher than the 25C and the adhesion temperature which the 5C is higher than adhesion temperature of the not yet processing pellet desirably at least.
