Producing a composite part contains joint partner including molded part made of a polyamide molding composition and a molded part made of a methacrylate copolymer molding composition comprising e.g. 2-methyl-propionic acid methyl ester

摘要

Producing a composite part comprises following joint partners: (a) a molded part made of a polyamide molding composition and (b) a molded part made of a methacrylate copolymer molding composition, which contains the following monomer units: 2-methyl-propionic acid methyl ester-2,3-diyl and e.g. 2-methyl-propionic acid-2,3-diyl , where the molded part (a) and (b) are joined together by laser welding, either (a) or (b) is adjusted by a content of nanoscale laser-absorbing inorganic particles or organic laser absorbing dyes. Producing a composite part comprises following joint partners: (a) a molded part made of a polyamide molding composition (50 wt.%) and (b) a molded part made of a methacrylate copolymer molding composition (50 wt.%), which contains the following monomer units: 2-methyl-propionic acid methyl ester-2,3-diyl (15-99.9 wt.%), 2-methyl-propionic acid-2,3-diyl, an anhydride derivative of formula (IV), 2-methyl-propionic acid oxiranylmethyl ester-2,3-diyl or 2-(4,5-dihydro-oxazol-2-yl)-propan-1,2-diyl (0.1-30 wt.%), where the molded part (a) and (b) are joined together by laser welding, either (a) or (b) is adjusted by a content of nanoscale laser-absorbing inorganic particles or organic laser absorbing dyes. m : 0 or 1.
