Mixtures (M), containing (A) phosphines of formula R<1>P(R)2 (I) and silicon compounds of formula R<2>aSi(OR<3>)b (II) in a mole ratio of 0.01-3.5, in which R = optionally substituted 6-14C aryl; R<1> = a group of formula -(CH2)nP(R)2 (Ia), -(CH2)nP(R)(CH2)mP(R)2 (Ib), -CH=CHP(R)2 (Ic), -C IDENTICAL CP(R)2 (Id), -ArP(R)2 (Ie)-(Ig) and -CH2C(Me)(CH2R(R)2)2 (Ih) (with Ar = 6-14C arylene; n, m = 1-7; with H atoms optionally replaced by F, Cl, Me, Et, cyclohexyl or Ph), or optionally substituted 4-phenylphenyl or naphthyl (if both R groups are 4-phenylphenyl or naphthyl); a + b = 4; b = at least 1; R<2> = H, 1-18C alkyl, 2-18C alkenyl, 6-24C aryl, or 7-24C aralkyl or alkaryl; R<3> = 1-18C alkyl, 2-18C alkenyl, 5-10C cycloalkyl or 7-24C aralkyl. Also claimed is (i) a process for the production of mixtures (M) by mixing the components together at 20-100 degrees C under inert conditions; (ii) thermoplastic aromatic polycarbonates (PC) containing 0.001-1 wt% (M), (iii) a process for the production of these PC compounds by mixing the PC during of after its production with mixture (M) in bulk or in solution, and then compounding on an extruder. |
