Process for preparing an impact-resistant thermoplastic moulding compound. |
摘要 |
<p>The invention concerns a simple, reliable and reproducable process for preparing an impact resistant thermoplastic moulding compound based on a copolymer consisting of styrene and/or alpha -methyl-styrene and maleic anhydride, characterized in that the moulding compound is prepared by mixing 50-95 % (wt) of a copolymer consisting of:
1. 50-95 % (wt) styrene and/or -methylstyrene
2. 50-5 % (wt) maleic anhydride
3. 0-20 % (wt) acrylate
4. 0-20 % (wt) acrylonitrile
with
5-50 % (wt) rubber modified with hydroxyl groups and 0-30 % (wt) unmodified rubber to be mixed in the presence of 0.01-10 parts by weight of a reaction accelerator, calculated on 100 parts by weight copolymer and modified rubber, at a temperature between 160 DEG C and 290 DEG C. </p> |
