Abstract: 1305121 Self-extinguishing moulding compositions BADISCHE ANILIN- & SODAFABRIK AG 19 June 1970 [20 June 1969] 29837/70 Heading C3R A self-extinguishing moulding composition comprises by wt.: #85% of a glass-fibrereinforced polyamide, and 0À5-15% red phosphorus. The polyamide has M.W. 15,000- 32,000, K values being 68-85, and contains units -NH-(CH 2 ) 5 -CO- and/or -NH- (CH 2 ) 6 -NH-CO(CH 2 ) 4 -CO-. The phosphorus may have av. particle-size 0À0005-0À5 mm.; it is of commercial grade and may contain #3% metal oxides and salts as stabilizing additive. Also present in the composition may be fillers, e.g. chalk, siliceous chalk, tale, heavy spar, quartz flour, slate flour, Sb 2 O 3 , Al 2 O 3 , silicic acid, glass balls, or coke flour; and pigments, e.g. lamp black, TiO 2 , Zn white, CdS, Fe oxides, MnO, MoS 2 , or graphite. The glass fibres have mean diameter 0À0006-0À02 mm. and may have length 0À2-10 mm. The composition may contain 1-50% wt. glass fibres.

Abstract: 1291636 Graft polymer compositions BADISCHE ANILIN- & SODA-FABRIK AG 6 March 1970 [8 May 1969] 10814/70 Headings C3G and C3P A moulding composition comprises a styreneacrylonitrile copolymer and a graft polymer of styrene and acrylonitrile on a backbone copolymer of a C 4 to C 8 alkyl acrylate and the acrylic ester of tricyclodecenyl alcohol, wherein said backbone copolymer used in the formation of the graft polymer is in the form of a latex of mean particle size 0À15 to 0À8 micron and showing a narrow particle size distribution. In the examples, the backbone copolymer is an n-butyl acrylate/tricyclodecenyl acrylate copolymer prepared in aqueous emulsion using a seed polymerization technique.
