    • A polymer composition containing (a) a high impact polystyrene (HIPS) component with a block copolymer grafted to polystyrene, a rubbery conjugated diene content of one to seven weight percent based on HIPS weight, less than 10 weight-percent gel concentration, an average rubber particle size of between one and 0.01 micrometers, about 40 to about 90 volume percent of the rubber particles have diameters of less than about 0.4 microns and from about 10 to about 60 volume percent of the rubber particles have diameters between about 0.4 and about 2.5 microns, a majority of rubber particles with a core/shell morphology and a concentration that accounts for 10 to 70 weight-percent of the total polymer composition weight and one to five weight-percent rubbery diene based on total polymer composition weight; (b) from 10 to 70 weight percent of a general purpose polystyrene and from about 2 to about 80 weight-percent of a styrene block copolymer component, both based on total polymer composition weight. In a film, preferably oriented, wherein the polymer composition accounts for at least 95 weight-percent of the film, with the balance of the film or film composition weight being additives. Shrink labels are made from the film.
    • 一种聚合物组合物,其包含(a)具有接枝到聚苯乙烯的嵌段共聚物的高抗冲聚苯乙烯(HIPS)组分,基于HIPS重量的1至7重量%的橡胶状共轭二烯含量,小于10重量%的凝胶浓度,平均 橡胶颗粒尺寸为1至0.01微米,约40至约90体积%的橡胶颗粒具有小于约0.4微米的直径,并且约10至约60体积%的橡胶颗粒具有约0.4至约2.5的直径 基于总聚合物组合物重量,具有核/壳形态和占总聚合物组合物重量的10至70重量%和1-5重量%橡胶二烯的浓度的大多数橡胶颗粒; (b)基于总聚合物组合物重量,10至70重量%的通用聚苯乙烯和约2-约80重量%的苯乙烯嵌段共聚物组分。 在薄膜中,优选取向,其中聚合物组合物占薄膜的至少95重量%,其余的薄膜或薄膜组合物重量为添加剂。 收缩标签由电影制作。
