Crystalline propylene/ethylene random copolymers containing a small proportion of ethylene are widely used and processed into various films, hollow bodies, injection molded products, and the like. In particular, it is widely used as a packaging material because it has better heat-sealing properties than FWE Lenhomorimer in fill packaging. However, the propylene/ethylene random copolymers conventionally provided cannot necessarily be said to have sufficiently high impact strength. In addition, if you try to obtain a heat-sealable taflopylene/ethylene lamem copolymer with a relatively low melting point by increasing the ethylene content, it will become sticky and the product will only have poor commercial value. A propylene/ethylene random copolymer in which the amount exceeds 5 moles is not commercially available.

As mentioned above, the decane soluble portion is slightly larger than that of similar commercially available random copolymers, and its intrinsic viscosity is within the range described above, so it has strong impact strength and may contain isolated ethylene. Even if the amount is relatively large, it has little stickiness and can be suitably used for molded products such as films. Note that here, the %-decane soluble portion is the random copolymer 10F to ItOs-f force y, 140
After uniformly dissolving (by heating for 8 hours at 23°C), the precipitated solid portion was left to cool overnight in a constant temperature bath at 23°C.
! The ratio can be determined by heating the exo-decane solution obtained by temporary separation at 3° C. to remove the exo-decane solvent and weighing the residue.

In the present invention, it is possible to provide a propylene/ethylene random copolymer which has the above-mentioned properties and also has very good fluidity. That is, D
It is possible to provide a copolymer powder having a powder fluidity index of &O or higher, preferably 90 or higher. Such a copolymer powder usually has a uniform shape and is particularly less sticky when applied. Since the above copolymer powder has good fluidity, it has the advantage that when it is manufactured by one slurry monopolymerization, it is easy to dry and can be dried stably without any trouble. Because of the ease of powder molding, which facilitates handling and molding, it can be shaped in a conventional manner if desired. Note that K (g) powder fluidity index is a value measured by a Powder Tester manufactured by Fine Powder Engineering Research Institute.

Comparative Example 112 Propylene-ethylene copolymerization was carried out using a catalyst system consisting of titanium trichloride and diethylalonitrium monochloride using hexane as a t-solvent. By changing the supply ratio of propylene and ethylene, polymer powder with an isolated ethylene content of &2 molar and a polymer powder with an isolated ethylene content of 4 molar
A 4 mol polymer powder was obtained. The liquidity index for this group is 7- and 6s, respectively. The results are shown in Table 1.
