Abstract (en)

[origin: EP2573142A1] Thermoplastic molding composition comprises (in wt.%, based on the components): (a) a thermoplastic (70-98), (b) a polymer mixture (2-30) comprising (i) at least one polyester based on aliphatic and aromatic dicarboxylic acids and an aliphatic dihydroxy compound (30-70), (ii) polylactic acid (70-30), (iii) an epoxy groups-containing copolymer based on styrene, acrylic acid esters and/or methacrylic acid (0-10), (iv) nucleating agents, lubricants and anti-blocking agents, waxes, antistatic agents, antifogging agents, or dyes (0-15), and (c) further additives (0-40). Thermoplastic molding composition comprises (in wt.%, based on the components): (a) a thermoplastic (70-98), (b) a polymer mixture (2-30) comprising (i) at least one polyester based on aliphatic and aromatic dicarboxylic acids and an aliphatic dihydroxy compound (30-70, based on the total weight of components (i) and (ii)), (ii) polylactic acid (70-30, based on the total weight of components (i) and (ii), (iii) an epoxy groups-containing copolymer based on styrene, acrylic acid esters and/or methacrylic acid (0-10, based on the total weight of components (i) to (iv)), (iv) nucleating agents, lubricants and anti-blocking agents, waxes, antistatic agents, antifogging agents, or dyes (0-15, based on the total weight of components (i) to (iv)), and (c) further additives (0-40). An independent claim is also included for increasing the impact strength of a thermoplastic (a), comprising mixing the components (a) thermoplastic, (b) a polymer mixture comprising polyester, polylactic acid, an epoxy groups-containing copolymer, nucleating agents, lubricants and anti-blocking agents, waxes, antistatic agents, antifogging agents, or dyes, and (c) further additives.
