Glass strengthening poly 4 - methyl - 1 - pentene constituent and glass strengthening denaturation poly 4 - methyl - 1 - pentene constituent

摘要

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. CONSTITUTION:Poly-4-methyl-1-pentene is compounded with 5-40wt% 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 0.1-15%, preferably 1-10% unsaturated carboxylic acid or its derivative (e.g. maleic acid, nadic acid, their anhydride, etc.) and having a melt flow rate of 1-500g/10min.
