| titleOfInvention | Polymer composition comprising a (meth)acrylic polymer having good optical properties and heat resistance |
| abstract | The present invention relates to a polymer composition comprising (a) 60.0-80.0 wt% of a (meth)acrylic polymer; and (b) 20.0-40.0 wt% of a copolymer prepared using styrene and maleic anhydride with regard to the total weight of (a) and (b), the total of (a) and (b) being 100 wt%; wherein the polymer composition is prepared by melt mixing of a mixture comprising (a) and (b) in a melt extruder, wherein the melt extruder comprises: (i) an inlet for feeding the mixture; (ii) a barrel comprising one or more extruder screw(s) each comprising a tip; (iii) one or more opening(s) for removing the obtained polymer composition from the extruder; and (iv) a volume of space in the area between the tip(s) of the extruder screw(s) and the opening(s) for removing the obtained polymer composition wherein during the melt mixing the temperature of the polymer composition in the volume of space (iv) is ≥ 235°C and ≤ 255°C. Such polymer composition has a desirable scratch resistance and a desirable heat resistance. |
