Abstract

Polymer stabiliser compsn. comprises (A) a solid continuous phase of amorphous tetrakis-(3-(3,5-di-tert butyl-4-hydroxyphenyl) propionyl-oxy-methyl) methane. Use as stabiliser is disclosed in e.g. US3644428. (B) Solid continuous phase, dispersed in (A) of amorphous or crystalline particulate organic phosphite, either of particle size 10 micron - 2 mm and m.pt. higher than (A) of formula (I) or of particle size 50 micron -2 mm and m.pt. over 100 deg.C of formula (II) or (III), where R1, R2, R3=opt. substd. alkyl, cycloalkyl, aryl, alkaryl or aralkyl gps. and R is chosen from gps. as R1, R2, R3. Wt. ratio (A) to (B)=1:9 to 9:1, esp. 3:7 to 7:3. Particle size of (B), pref. 100-500 micron. More specifically (B) is e.g. triphenyl phosphite, tris(2-tert. butylphenyl)-phosphite, distearyl pentaerythritol diphosphite (14 cpds. claimed).
