    Abstract: A process for the continuous colour measurement of plastic articles by means of a device (I) is new. Light is conducted via a transmitter optical fibre (II) and a sensor head (III) into the plastic melt and the reflected light is guided via a receiver optical fibre (IV) to a spectrometer or multi-range photometer (II) and (IV) are arranged such that they are the same distance apart from each other. Also claimed is (I).

    Abstract: Compsns. (I) contain, on wt. of compsn. from (A) + (B) + (C), (A) 30-70 wt.% at least one polymer contg. styrene, opt. substd., (B) 30-70 wt.% polyethylene, and (C) 1-20 wt.% stellate block copolymer of 55-90 wt.% styrene and 45-10 wt.% butadiene, produced by anionic polymerisation with coupling, having average star branching no. 3-12. (I) consists of (A), (B), and (C). (A) is impact-resistance polystyrene (II). (B) is high density polyethylene. (C) has average mol. wt. (GPC) 100,000-300,000. (I) also contain 0.05-50 pts. wt. conventional additives. (C) has polymodal compsn. and individual star branch styrene-butadiene block copolymers have either sharp or blurred transitions between the blocks of styrene and butadiene.
