Abstract

Articles of isotactic polystyrene having enhanced crystalline rates are made by blending isotactic polystyrene with at least 1% of a plasticizer which is a polymer of styrene, o- or p-chlorostyrene, p-bromostyrene, a -methylstyrene, p-methyl-a -methylstyrene, 3,4-dichloro-a -methylstyrene and/or a mineral oil of b.p. at least 200 DEG C. and consisting mainly of saturated aliphatic hydrocarbons and forming the mixture, e.g. at 100-300 DEG C., into an article which is then annealed at 100-200 DEG C. for 1/2 -2 hours to effect crystallization. The plasticizer may be a colourless mineral oil of viscosity 10-71 cs. at 38 DEG C., a -methylstyrene dimer or poly-a -methylstyrene of viscosity 100-1000 cp. at 60 DEG C.
