| titleOfInvention | Polymethacrylate moulding matters stabilised against discolouration at thermal stress |
| abstract | A moulding compsn. contains (a) 100 pts. wt. of a copolymer from (i) 50-98C wt.% of a 1-6C alkyl methacrylate, (ii) 1-25 wt.% of a vinylaromatic cpd., (iii) 1-25 wt.% of maleic anhydride and (iv) 0-5 wt.% of a 1-6C alkyl acrylate, and (b) 0.001-2 pts. wt. of an organic phosphite contg. a sterically hindered phenoxy substit. linked covalently with P through O. Pref. the phosphite is of formula (I) or (II), where R1, R2, R'2 = 1-6C alkyl, pref. tert. butyl; R'1 = H or 1-6C alkyl, pref. tert. butyl; and R3, R'3 = H or 1-10C alkyl, pref. R'3 = Me. The monomers are (i) methyl methacrylate and (ii) styrene and/or methylstyrene. |
