    Abstract: A calanderable, thermoplastic moulding compsn. contains (A) at least 95 wt.% of a non-elastomeric, star-shaped, branched block copolymer from (a) 60-95 wt.% of styrene and (b) 40-5% of a 4-5C conjugated diene, obtd. by sequential anionic polymerisation of (a) and/or (b) with an organo-Li cpd. as initiator in presence of a solvent, followed by coupling, (B) up to 0.2% of an amide of stearic acid or erucic acid as anti-blocking agent, (C) 0.05-2% of a sterically hindered phenol as stabiliser, and (D) 0.05-2% of a stearate of Sn, Ca or an alkali metal as lubricant. USE/ADVANTAGE - The compsns. can be calandered to transparent films with a good surface and uniform thickness. The films do not adhere to the rollers and can be withdrawn from the last calander roller without overrun. The films have a quality similar to that of extruded films, can be deep-drawn and can be used for all the applns. of extruded films. The compsn. is used for prodn. of films.
