摘要： A plastic molded product of olefin (co)polymer composition comprises 0.01-5.0 weight parts high molecular weight polyethylene with an intrinsic viscosity &eegr;E in the range of 15-100 dl/g measured in 135° C. tetralin and preferably 100 weight parts polypropylene. The high molecular weight polyethylene has an average particle size in the range of 1-5000 nm and is finely dispersed as fine granules in the polypropylene, so that high melt strength and high crystallization temperature are attained, enabling various molding methods to be performed with high speed productivity. Using the polymer composition, plastics such as a resin foam, a film, a sheet, a layered plastic article with a coated substrate surface, a hollow plastic article, an injection molded plastic article, a fiber, a nonwoven web or a continuous tube-shaped plastic are provided. The olefin (co)polymer composition is obtained by preparing high molecular weight polyethylene granules using e.g. a titanium transition metal compound catalyst, and adding these, e.g. as a polymerization catalyst of propylene, singly or together with a polyolefin preparing catalyst.

摘要： [Problems] Provided is a configuration in which a member is not interposed between exhaust gas and a partition wall of an engine coolant passage, and the exhaust gas is caused to directly collide with the partition wall of the engine coolant passage, thus raising the gas flow velocity in a heat exchange part, which enables further improving the exhaust heat recovery rate.[Means for Solving Problems] An engine exhaust gas heat recovery device (1) recovers heat from engine exhaust gas by performing heat exchange between the engine exhaust gas and engine coolant. A plurality of spray holes (20) facing an inner cylinder tube (31) of a coolant passage (3) have been provided in an outer tube (22) of an exhaust gas inflow tube (2), and the exhaust gas is caused to directly collide with the inner cylinder tube (31) of the coolant passage (3). A minimum distance from each of the spray holes (20) to the inner cylinder tube (31) of the coolant passage (3) is in a range of 1.5 to 7 times the diameter of the spray holes. A relationship between a total opening area of the spray holes (20) and an exhaust gas flow rate is (total spray hole area/exhaust gas mass flow rate)=2.0 to 4.5 (cm2/(kg/min)).
