A process for the consolidation of discrete, particulate, low-melting or liquid materials, characterized in that said materials are consolidated in their particulate discrete form by application of vapors of at least one p-xylylene monomer and/or of a derivative thereof, which is polymerized under vacuum. The materials are thus given the surface characteristics of a solid, with enhanced properties of mechanical, physical and/or chemical strength, even in the presence of high temperatures. The invention is particularly useful for the metered addition of predetermined amounts of compositions or for moving mechanical parts.

Process of consolidating low-melting materials

Process for consolidating solid materials and/or articles, which exhibit at least a low cohesion degree area associated with at least one structural discontinuity, debouching or opening into the surface and/or pervious from the surface of said material and/or article, with ports or openings having sizes equal to at least 0.01 micron, which process comprises:

Process for consolidating discontinuous-structured materials

Containers with low permeability to hydrocarbon vapors, and in particular to fuel vapors, having at least one surface coated with a p-xylylene polymer and/or its derivatives. The containers find use in the fuel industry and, in particular, in the automobile industry for the production of fuel tanks for cars, commercial vehicles, and motorcycles.

Containers having low permeability to hydrocarbon vapors and process of

Process for the adhesion of para-xylylene vapors to solid substrates by the use of an unsaturated ester of phosphoric acid of the formula: ##STR1## wherein at least one of the radicals R.sub.1, R.sub.2 and R.sub.3 is hydrogen and at least one of said radicals is:
