Description

Podobne efekty, choc uzys¬ kane pod warunkiem niezwykle dokladnego wymie¬ szania skladników w czasie stapiania, otrzymuje sie 30 stosujac zywice dwufenylopropanowa modyfikowa- 7222272222 3 na kalafonia i a&tryifikowaina gliceryna (Balitol CG-7), zywice krezolofoTmaldehydowa modyfikowa¬ na kalafonia (Baitol KF1) oraz zywice kalafoniawo- -mialeinowa estryfikowana gliceryna (Polomai MA56).Pierwsze trzy dodawane sa w ilosciach 5—10%, ostatnia, powodujaca równiez obnizenie temperatu¬ ry topnienia, dodawana jest w ilosci 20—30%.Przyklad I. 87 cz. polistyrenu, 5 cz. Polimalu 13i6, 8 cz. sadzy stapia sie, a po schlodzeniu rozdrab¬ nia do wielkosci ziaren 2—20 nm, a najlepiej 5—15 lim.Przyklad II. 87 cz. kopolimeru styren-meta- krylan butylu, 5 cz. zywicy krezoloformaldehydo- wej modyfikowanej kalafonia i(Baltol KR-1), 0 cz. sadzy, dokladnie rozdrobnionych i wymieszanych 10 15 stapia sie, intensywnie miesza, chlodzi i rozdrabnia na czastki o wlasciwej wielkosci. PL PLSimilar effects, although obtained under the condition of extremely thorough mixing of the components during melting, are obtained by using a diphenylpropane resin modified with rosin and a & tri-glycerin (Balitol CG-7) resins, cresolophyltmaldehyde resins (Baitol). ) and rosin-myaline resin esterified glycerin (Polomai MA56). The first three are added in an amount of 5-10%, the last one, which also reduces the melting point, is added in an amount of 20-30%. polystyrene, 5 pcs. Polimalu 13i6, 8 pcs. The soot is melted and, after cooling, it is ground to a grain size of 2-20 nm, preferably 5-15 µm. Example II. 87 part styrene-butyl methacrylate copolymer, 5 parts modified cresolformaldehyde resin rosin i (Baltol KR-1), 0 pc. soot, finely crushed and mixed 10 15 is melted, intensively stirred, cooled and ground into particles of the correct size.
