From the calculation of the total composition of the molding compositions of Table 3, it follows that these molding compositions each contain 20% by weight of A components (Al and A-2), 76.4% by weight of B components (BI and B-2 ) and 3.0% by weight of C components (CI to C-5). Table 3 Compositions and their properties
- the mixing of the components is carried out on a twin-screw extruder (ZSK25 Fa. Werner and Pfleiderer) at a melt temperature of 250 0 C to 257 0 C and a throughput of 15 kg / h.
- the resulting mixture is granulated and dried.
- the moldings are (unless otherwise described) at 260 to 280 0 C and mold temperatures of 70 to 90 0 C on an injection molding machine type Arburg 270 E manufactured.
- thermoplastic molding compositions The composition and properties of the non-inventive thermoplastic molding compositions are shown in Table 5. From the calculation of the total composition of the molding compositions of Table 5, it follows that these molding compositions in each case in total about 17 wt .-% of A components, 79.5 wt .-% of B components, 3.0 Wt .-% of C-components and 0.55 and 0.6 wt .-% of D components included.
- the process according to the invention it is very efficiently possible to incorporate the glycidyl ester copolymer (component C) in quantities of more than 30% by weight into the polyalkylene terephthalate or polycarbonate.
- component C glycidyl ester copolymer
- Tables 2 on the basis of the filled glycidyl ester copolymers CoPE-a to CoPE-h according to the invention, it is also possible to use the process according to the invention without negative effects on the gloss of the resulting molded articles (see Table 3). 50 wt .-% glycidyl ester copolymer produced and processed.
- Polyalkylene terephthalate is carried out in the first step in the melt according to the usual compounding methods, is a concentration of about 30 wt .-% in the Not to achieve overall composition of the molding, since with increasing content of glycidyl ester copolymer, the extruded melt is unstable to segregation (phase separation), before the solid state state is reached.
- a further disadvantage of melt mixing is that in the melt, the end groups of the polyalkylene terephthalate can react with epoxide groups of the glycidyl ester copolymer and thus cause the formation of large, difficult-to-disperse particles which, after further processing, improve the gloss reduce the resulting molding.
