We report a new measurement of analyzing powers for the reaction
$\\vec p+CH_2\\to$ one charged particle +$X$, at proton momenta of
1.75, 3.8, 4.5 and 5.3 GeV/c. These results extend the existing
data basis, necessary for proton polarimetry at intermediate
energy, and confirm the feasibility of a large acceptance polarimeter
based on this process.
The experiment is performed
at the accelerator complex of the JINR-LHE (Dubna).
