摘要： The invention relates to novel molding compounds based on partially crystalline technical thermoplastics, which allow to produce laser-markable molded articles having increased quality of marking. The molding compounds are characterized by comprising, in a polymer matrix (A) microscale or nanoscale primary particles of photosensitive compounds having a plurality of cations (B) and/or nanoscale primary particles of photosensitizing oxides (C) and optionally other additives (D). The invention also relates to molded articles that are produced from the inventive laser-markable molding compounds, to a method for laser marking and to the use of selected additives for laser marking.

摘要： The invention relates to a device for producing oxymethylene-homo-and-copolymers. Said method consists of heterogeneously polymerising a monomer forming oxymethylene groups together with an acetal of formaldehyde and an initiator of the cationic polymerisation, then deactivating the polymer in the homogeneous phase by treating it with a basic aprotic solvent or with an aprotic solvent which contains a base. The invention also relates to oxymethylene-homopolymers having a very high stability.

摘要： The invention relates to a method and to a device for producing oxymethylene-polymers. Said method consists of polymerising monomers forming oxymethylene groups together with an acetal of formaldehyde and an initiator of cationic polymerisation in the homogeneous phase upto 90 % of the maximal conversion, and deactivating the reaction mixture. The obtained oxymethylene-polymers comprise alkyl ether-end groups and are extremely stable.

摘要： The invention relates to novel halogen-free flameproof thermoplastic molding compounds which allow to produce laser-marked molded articles having an increased marking quality. The molding compounds are characterized by comprising at least one thermoplastic (A) and at least one photosensitive saline compound which changes its color in the polymer matrix or which leads to a color change in the polymer matrix when exposed to laser light (B1); and/or at least one photosensitive or photosensitizing oxide which changes its color in the polymer matrix or which leads to a color change in the polymer matrix when exposed to laser light (B2); and at least one halogen-free compound or mixture that positively influences the flammability and fire behavior of the molding compound (C); and optionally other additives (D). The invention relates to molded articles that are produced from the inventive laser-marked flameproof molding compounds and to laser-marked molded articles produced therefrom. The invention also relates to a method for laser-marking and to the use of the laser-markable, flameproof molding compounds for producing laser-marked molded articles.
