Olefin/ester copolymer blend and blend which possess environmental stress cracking or the environmental fatigue tolerance which is improved manner, formation manner null of the product and the aforementioned product which are produced from now on

摘要

Product having flexibility and blends prepared from the copolymer (57) of two ethylenically unsaturated carboxylic acid ester monomers and olefins Abstract]. Each copolymer should include an ethylenically unsaturated carboxylic acid ester monomers than 6% by weight, the copolymer is selected to be 10 wt% of the blend. Ester content of the same, that is if the copolymer is less than 6% difference, then the copolymer is selected difference in the melt flow to be about greater than 8. Ester content dissimilar, that is if the copolymer difference exceeds 6 wt%, then the copolymer is selected ratio of the melt flow to be about 2 or less.
