A block or assembly of blocks of synthetic foam is waterproofed over part of its lower and side base with the aid of a waterproofing agent which enters the foam partially and deposits a water-repellent film on the treated outer surface. A block of phenolic foam is waterproofed with an acrylic latex to produce supports for floral arrangements. Slabs of polyurethane foam are assembled with inserts a...

Novel fluorine-containing polyorganosiloxanes comprise repeating units of the formula [F(CF2)m(CH2)n]pSiO(4-p)/2, R3SiO1/2 and SiO4/2 where R represents a monovalent hydrocarbon radical containing from 1 to 20 carbon atoms, m has an average value from 1 to 20, n is 1 or 2 and p is 1, 2 or 3. The polyorganosiloxanes are particularly useful as stabilizers for foams prepared by introducing gaseous bl...

A novel film made from a latex having an exceptional balance of physical properties is prepared by polymerizing an unsaturated dicarboxylic acid with a copolymerizable monomer(s) and, optionally, a crosslinking monomer in the presence of an effective amount of a surfactant and an initiator. In a preferred embodiment of the process for making the film, all of the unsaturated dicarboxylic acid is in...

The method uses drilling machinery consisting of a train of rods (2) supporting a drilling tool (5) at its end. The machinery carries out drilling which defines an annular space (7) between the train of rods and the wall of the drill-hole. A control system governs the flow rate or the pressure. A pipe (14) enables the annular space to be put into communication with the control system. Means (24) a...

There is disclosed a process for preparing calcium sulphate having a particle size distribution such that at least 50% by weight of the particles have an equivalent spherical diameter smaller than 2 microns, which process comprises the following steps: (a) mixing a relatively coarse calcium sulphate with water to form an aqueous suspension containing from 5 to 45% by weight of dry solids; (b) co...
