- 1. By way of a new product, the substituted polystyrene of the formula ##STR28## in which x, y, z and t are numbers such that x+y+z+t=1, 0<x<0.9, 0<y<0.5, 0.03<z<1.0 and 0<t/z<0.4, Z being a sulphur or oxygen atom, X being a chlorine or bromine atom and R.sub.1 and R.sub.2 being linear or branched C.sub.1 to C.sub.18 alkyl groups, preferably C.sub.1 to C.sub.12 groups and in particular octyl groups in both cases, for a number-average molecular weight Mn such that 20,000<Mn<1,000,000.
- 2. By way of a new product, the substituted polystyrene of the formula ##STR29## in which 2<p<12, v, w, x', y' and z' are numbers such that v+w+x'+y'+z'=1, v/y'+z'+w<0.1, 0<x'<0.7, 0<y'<0.4, 0<z'<0.1 and 0.03<w<0.9, X=Cl or Br, Z=O or S, R.sub.1 and R.sub.2 are identical or different and are a linear or branched C.sub.1 to C.sub.18, preferably C.sub.1 to C.sub.12, alkyl group or a C.sub.7 to C.sub.10 arylalkyl group, and A is a phenyl nucleus of a polystyrene chain of the same type, the groups A' being in some cases a group X and in other cases a group --PZR.sub.1 R.sub.2, Z, X, R.sub.1 and R.sub.2 having the above meanings.
