Provided is a polychloroprene latex extremely favorable in adhesive properties.The present invention relates to a method of producing a polychloroprene latex, comprising polymerizing chloroprene or a mixture of chloroprene and a monomer copolymerizable with chloroprene in an aqueous medium containing a surfactant at a concentration of lower than its critical micelle concentration (CMC) and a polymer dispersant of a metal salt of aromatic sulfonic acid formalin condensate added thereto. The polymer dispersant for use is preferably a metal salt of aromatic sulfonic acid formalin condensate. The polychloroprene latex obtained can be used as an adhesive.

Provided is a polychloroprene latex extremely superior in adhesion properties.According to the present invention, chloroprene or a mixture of chloroprene and a monomer copolymerizable with chloroprene is polymerized in the presence of a surfactant in an aqueous medium, in which the surfactant's concentration is lower than its critical micelle concentration (CMC) to obtain a polychloroprene latex. The polychloroprene latex produced according to the present invention is extremely superior in adhesion properties and others and give a smaller amount of deposits during production.

摘要:
A wheel includes a hub, a rim, and spokes. The hub includes inner attachment portions and is configured to support the wheel about a rotational axis. The spokes are attached to the hub and the rim and are together configured to radially support the rim with respect to the hub. In one embodiment, the spokes are attached to the hub with fasteners extending into threaded apertures in the hub, and the spokes are attached to the rim with fasteners extending in a direction parallel with the rotational axis. In another embodiment, respective ones of the spokes, which are attached to a common inner attachment portion of the hub, are not attached to adjacent outer attachment portions of the rim. Vehicles and methods of manufacturing a wheel are also provided.
摘要:
A motorcycle includes a main frame having left and right main frame members which each extend obliquely downwardly and rearwardly from a forward end to a rearward end. The forward end of the main frame includes a steering interface and the rearward end of the main frame includes a swingarm interface. An engine is attached to the main frame. A swingarm is attached to the swingarm interface and supports a rear wheel. A seat is attached to the main frame at an attachment location. The main frame, the swingarm, and the seat together at least partially define an open space of sufficient size to facilitate substantially complete access to the second cylinder head when the motorcycle is fully assembled.
摘要:
A motorcycle includes a frame, a fork, a from wheel, an upper arm, a lower arm, a handlebar, and a suspension element. The fork is pivotable with respect to the frame about a steering axis. The front wheel is rotatably coupled with the fork. The upper arm and the lower arm are each pivotally coupled with each of the fork and the frame. The handlebar is pivotally coupled with the frame and is configured to facilitate steering of the front wheel. The suspension element is coupled with each of the frame and the fork.
