Abstract
A method for producing a melt-kneaded composition that includes performing melt-kneading of 3-methyl-1-butene polymer and an alkyl radical scavenger, in which the melt-kneading is performed at 300 to 380° C., and in which the melt-kneading is performed by injecting an inert gas into a melt kneader or the melt-kneading is performed by degassing the inside of the melt-kneader under reduced pressure, and a melt-kneaded composition.
Claims13
A method for producing a melt-kneaded composition comprising:
- performing melt-kneading of 3-methyl-1-butene polymer and an alkyl radical scavenger at 300 to 380° C. under a lower oxygen state than that of atmospheric air.
A method for producing a melt-kneaded composition comprising:
- performing melt-kneading of 3-methyl-1-butene polymer and an alkyl radical scavenger,
- wherein the melt-kneading is performed at 300 to 380° C., and
- wherein the melt-kneading is performed by injecting an inert gas into a melt-kneader, or the melt-kneading is performed by degassing the inside of the melt-kneader under reduced pressure.
