Flame retarded polyacrylimide or polymethacrylimide resin foams containing at least 70 percent by weight of cyclic acrylimide or methacrylimide units and incorporating at least 1 percent by weight of phosphorus, present at least partially in the form of a phosphorus compound, XCH2-PO(OR)2, wherein R is methyl, ethyl, or chloromethyl, and X is hydrogen, halogen, hydroxyl, or RO-CO-.

The invention relates to the process of the invention provides a radiation-crosslinked polypropylene foam by extrusion at a low temperature (about 170 DEG C.) below the decomposition point of the blowing agent. The resulting foamed item has by far better heat resistance than conventional ones. The raw resin can be prepared by mixing a resin in the pellet form and a blowing agent in the powder for...

A system for determining the stuck point of pipe in a borehole includes a wireline tool having an exciter coil and a detector coil axially spaced from one another. The exciter coil 61 is driven by an oscillator 81 at a preselected low frequency, and the resulting voltage induced into the receiver coil 63 is related to the magnetic permeability of a pipe 60 through which the tool is run. A detector...
