摘要:
A polyolefin resin composition comprises a component A consisting of polypropylene or a propylene-ethylene block copolymer whose MFR is greater than 16 (g/10 minutes); a component B consisting of an ethylene based rubber; and a component D compatible with the component B. A ratio of summation of the propylene-ethylene copolymer part in the component A, the component B, and the component D to summation of the components A, B, and D is 25 wt. % or more and 45 wt. % or less. Further, a ratio of the blend quantity of the component D to summation of the blend quantities of the components B and D is less than 0.8. In this manner, the bending elastic modulus and the tensile breaking extension are included in a desired region, while the tensile breaking extension is improved.

The invention provides a structure of a front part of a vehicle body that is simple and free from the risk of maloperation. In the event of a collision between the vehicle and a pedestrian, a projecting part sweeps the pedestrian by parts of his or her legs lower than the knees in the event of a collision between the vehicle and the pedestrian, causing the pedestrian to be thrown over toward the vehicle, and after an energy-absorbing member has absorbed impact energy exerted on the legs, the pedestrian is caused to drop onto the top of a hood and protected from secondary damage. In one specific example, a structure of a front part of a vehicle body in which a bumper (9) is provided at a lower front position of a hood (1) of the vehicle comprises a lateral supporting member (7) provided in the front part of the vehicle body and extending in the direction of vehicle width, an energy-absorbing member (8) provided ahead of the lateral supporting member (7), and a projecting part (12) provided at a lower part of the bumper 9 in such a manner that a forward end of the projecting part (12) juts out more frontward than the lateral supporting member (7).

An injection molding composition includes: 100 parts by weight of a propylene-ethylene copolymer comprising a crystalline portion and a non-crystalline portion; and 17 to 33 parts by weight of inorganic particles capable of imparting at least one of rigidity and heat resistance to the propylene-ethylene copolymer. The propylene-ethylene copolymer has a melt flow rate of 15 to 50 g/10 min and a molecular weight distribution (Mw/Mn) of not less than 5. A crystalline ethylene polymer contained in the crystalline portion and a non-crystalline propylene-ethylene copolymer contained in the non-crystalline portion have a total amount ranging from 10 to 20% by weight.
摘要:
A molding made of a thermoplastic resin composition that comprises a thermoplastic resin component and an elastomer component partly blending in with each other is continuously heated at a temperature higher than 120° C. but lower than a melting point of each of the two components for at least one hour so as thereby to cause the thermoplastic resin component to separate and precipitate in the elastomer component.

A method for producing an α-olefin oligomer including: polymerizing in the presence of a catalyst one or more α-olefins having 6 to 20 carbon atoms to produce an α-olefin oligomer; and deactivating the catalyst by a deactivator from which oxygen is removed. A method for producing an α-olefin oligomer including: polymerizing in the presence of a catalyst one or more α-olefins having 6 to 20 carbon atoms to produce an α-olefin oligomer; and passing the reaction solution containing the α-olefin oligomer through a bag filter.
