    摘要: A high roof structure of a vehicle includes a high roof formed from a RFP (Fiber Reinforced Plastics) with good durability, forming properties, and a reinforced structure is integrally installed using a predetermined adhering member and engaging member. No welding is needed. An indoor height of a vehicle is increased to a desired size and a desired indoor floor space index is obtained.

    摘要: This invention relates to a process for preparing styrene-butadiene rubber or butadiene rubber with both ends of the polymer chain modified by solution polymerization, wherein styrene-butadiene rubber or butadiene rubber is polymerized using a monofunctional anionic polymerization initiator modified with amines or the like, and then the active anion at the ends of the polymer chain is reacted with the commonly available modifier. Unlike a bifunctional initiator that shows a poor solubility in a nonpolar solvent, an increase in viscosity and loss of modification efficiency induced by impurity, styrene-butadiene rubber or butadiene rubber by solution polymerization can be prepared using the modified anionic polymerization initiator of the invention.
