Polymer mixture (A) comprises a low molecular (meth)acrylate(co)polymer (I); shock resistant modifying agent (II) based on cross linked poly(meth)acrylate; high-molecular (meth)acrylate(co)polymer (III); and/or a further (meth)acrylate(co)polymer (different from (I)). Polymer mixture (A) comprises a low molecular (meth)acrylate(co)polymer (I) with a solution viscosity, in chloroform, at 25?C (international standard organization (ISO) 1628 - parts 6) of less than or equal to 55 ml/g; shock resistant modifying agent (II) based on cross linked poly(meth)acrylate; high-molecular (meth)acrylate(co)polymer (III) with a solution viscosity, in chloroform, at 25[deg]C (ISO 1628 - part 6) of greater than or equal to 65 ml/g; and/or a further (meth)acrylate(co)polymer (different from (I)) with a solution viscosity, in chloroform, at 25[deg]C (ISO 1628 - part 6) of 50-55 ml/g (where: (I), (II), (III) and/or (IV) exist as individual polymer or as polymer mixture; (I), (II), (III) and/or (IV) are added to make up to 100 wt.%; (A) further comprises common additives, auxiliaries and/or fillers; and a sample substance produced from (A) shows the characteristics such as tensile module (ISO 527) of at least 2500 MPa, Vicat softening temperature (ISO 306-B50) of at least 110[deg]C, impact strength (ISO 179, edgewise) of at least 30 KJ/m 2>, and a melt index (ISO 1133, 230[deg]C/3.8 kg) of at least 1 cm 3>/10 min. Independent claims are also included for: (1) a kernel-shell-particle comprising a kernel (comprising 75 wt.% of (meth)acrylate repeating units), first shell (exhibiting a glass transition temperature of less than 30[deg]C; and comprising 92-98 wt.% of (meth)acrylate repeating units and 2-8 wt.% of styrolic repeating units (both added to give 100 wt.%)) and a second shell (comprising 75 wt.% of (meth)acrylate repeating units of formula (I)) (where the radius of the kernel-shell-particle including the second shell, measured using Coulter-procedure, is greater than 160-250 nm); and (2) an injection molding molded article comprising (A). R 1>-R 5>H, halo, 1-6C alkyl or 2-6C alkenyl; and R 6>H or 1-6C alkyl. [Image]. |
