A carbon material precursor comprises an acrylamide-based polymer having a weight-average molecular weight of 10,000 to 2,000,000 and a polydispersity of the molecular weight (weight-average molecular weight/number-average molecular weight) of 5.0 or less.

A composition based on poly(arylene ether ketone) (PAEK) which is stable in the molten state, characterized in that it includes a phosphate salt or a mixture of phosphate salts, a process for the stabilization of a composition based on PAEK incorporating said phosphate salts and objects manufactured using the composition.

A scrim is described comprising a plurality of fibers and a coating disposed on the scrim wherein the coating comprises a binder and a flame retardant additive. The scrim has a basis weight less than or equal to 200 grams/m.sup.2 and passes the UL94-V0 flammability standard. The scrim may be incorporated into other articles and methods. Also described is a flame retardant coating composition.

A method for stabilizing a composition made from PAEK, said method including a step of incorporating a stabilizing agent against thermo-oxidation phenomena, said method being characterized in that said incorporated stabilizing agent is a phosphate salt, or a mixture of phosphate salts. The phosphate salt is incorporated into the composition based on PAEK by one of the following techniques: dry blending, compounding, wet impregnation or during the process for synthesizing the PAEK polymer.

It has been found, that when co-absorbing substances are added to intrinsic laser-absorbing bismuthoxide, the marking performance with a Nd.YAG-laser is improved or at least kept at the same level by reducing the costs. It is suspected, that the co-absorbing additive is not simply adding a contrast to the polymer by carbonizing the surrounding polymer but helping the bismuthoxide to couple the laser radiation and to ease the color change of this additive. This so found effect helps to cheapen the replacement of antimony trioxide and therewith have a safer and more sustainable solution for the current and future technology of laser marking.

A carbon material precursor includes an acrylamide/vinyl cyanide-based copolymer which contains 50 to 99.9 mol % of acrylamide-based monomer unit and 0.1 to 50 mol % of vinyl cyanide-based monomer unit; a carbon material precursor composition includes the above-described carbon material precursor and at least one additional component selected from the group consisting of acids and salts thereof; and a method for producing a carbon material, includes subjecting the above-described carbon material precursor or the above-described carbon material precursor composition to thermal-stabilization treatment as necessary, followed by carbonization treatment.
