PURPOSE: To produce the titled composition having improved mechanical properties, etc. without deteriorating the transparency, by compounding a glass reinforcing material composed mainly of silicon dioxide to the base resin. n CONSTITUTION: Poly-4-methyl-1-pentene is compounded with 5W40wt% glass reinforcing material containing ≥95% silicon dioxide. The base resin may contain a modified poly-4-methyl-1-pentene grafted with an unsaturated carboxylic acid or its derivative. The modified resin is the one grafted with 0.1W15%, preferably 1W10% unsaturated carboxylic acid or its derivative (e.g. maleic acid, nadic acid, their anhydride, etc.) and having a melt flow rate of 1W500g/10min. n COPYRIGHT: (C)1985,JPO&Japio |
