     wherein R' represents at least one hydrophobic group having a hydrophobic fragmental constant of at least 1.5, which copolymer has a high crosslinking monomer units content, a specific surface area and a specific acetonitrile regain value. The hydrophobic crosslinked copolymer has a high rigidity as well as an excellent mechanical strength and an excellent chemical stability so that the copolymer is useful as a packing for liquid chromatography, particularly reversed phase partition chromatography. This hydrophobic crosslinked copolymer can be advantageously produced by a method in which a crosslinked copolymer having a side chain of small. length is first produced, and then a substitution reaction to introduce a hydrophobic group of large length is effected with respect to the side chain of small length.

Abstract: A multi-point wall thickness gage (10) comprises a pad (16) of flexible magnetic material that includes an array of ultrasonic transducers (13) and a multi-point ultrasonic transmitter and receiver (25) to which each transducer (13) is attached. The magnetic pad (16) is attachable to the wall of a ferro-magnetic object (19), and serves to hold the array or matrix of ultrasonic transducers (13) against the wall of the object. The specific region of the object wall being inspected is marked off (17), and the magnetic pad (16) is periodically applied over this region (17). The output of the transducers (13) is used to detect whether any wall thinning is occurring over the particular area of the object covered by the magnetic pad (16), and if so, the particular pattern of thinning within the area. Trend monitoring is simplified since exact relocation of the transducers (13) for periodic measurements is more readily accomplished.
