摘要： A vinyl monomer is graft polymerized on an aromatic hydrocarbon-based polymer film substrate to introduce graft chains into the substrate and thereafter a functional monomer represented by the following formula and having sulfonic acid groups or functional groups capable of conversion to sulfonic acid groups is graft polymerized to introduce the sulfonic acid groups or the functional groups capable of conversion to sulfonic acid groups: where R is an aromatic ring or an aliphatic chain; X is (1) —OH, (2) —OLi, —ONa or —OK, (3) —F or —Cl, or (4) —OCnH2n+1 where n is an integer of 1 to 7. Since the graft chains obtained by graft polymerization of the vinyl monomer can also be utilized as scaffold polymers, the graft polymerizability of the functional monomer to the aromatic hydrocarbon-based polymer film substrate is sufficiently improved to enable the preparation of a polymer electrolyte membrane that excels not only in proton conductivity and mechanical strength but also in dimensional stability.

摘要： The present invention discloses a fast inflating air pump, including a housing, an inflating tube, an inlet tube, a motor, a transmission assembly and a controller housed in the housing. A blower is arranged in the inlet tube for increasing air pressure to the inflating port. A piston is at least partially contained in the inflating tube, and the piston is driven by the motor via the transmission assembly so as to slide back and forth linearly for increasing air pressure in the inflating tube. A one-way valve is installed in the communicating pipe for only allowing air flow into the inflating tube. The controller instructs the motor to drive the piston to slide back and forth in the inflation tube on condition that the blower stops working until the air inflation pressure increases to a predetermined threshold, then the controller instructs the motor to stop operating.
