    摘要: A method for making a syndiotactic vinylaromatic polymer. The method includes mixing a first amount of a vinylaromatic monomer with a catalyst in a first back-mixed reaction zone under polymerization conditions such that the vinylaromatic monomer polymerizes to a conversion of from 60 to 85 percent to form a polymer-containing mixture. The polymer-containing mixture is passed to at least one other back-mixed reaction zone where it contacts a second amount of the vinylaromatic monomer under polymerization conditions such that the syndiotactic vinylaromatic polymer is formed.

    摘要: A trailer hitch guide adapted to enable a vehicle operator to hitch a trailer to a vehicle without assistance and without leaving the confines of his cab. The guide assembly includes a mounting plate and a pivot plate adapted for attachment to a trailer tongue and two lateral guide plates pivotally attached to the pivot plate in a V-shaped configuration. A stop plate is disposed across the base of the V-shaped configuration. In use, the hitch guide pivots to an extended position beneath the hitch socket at the end of the trailer tongue to guide the ball under the socket, and pivots to a retracted position beneath the trailer tongue after alignment.
