There are disclosed a styrenic block copolymer having a reduced viscosity of 0.01 to 20 dl/g (0.05 g/l in 1,2,4-trichlorobenzene at 135°C) which comprises highly syndiotactic styrenic-polymer segments and 10⁻⁴ to 10 mol% of heteroatom-containing styrenic polymer segments; a resin composition comprising the above styrenic block copolymer and a thermoplastic resin, an inorganic filler or an organic filler; a multi-layer material comprising at least one layer composed of the above styrenic block copolymer or the above resin composition; and a process for producing the above styrenic block copolymer which comprises polymerizing a styrenic monomer in the presence of a specific catalyst and adding a heteroatom-containing styrenic monomer to successively proceed with copolymerizaiton reaction. The above-disclosed styrenic block copolymer and the resin composition exhibit excellent compatibiity and adhesivenesss, and the multi-layer material is expected to find a wide range of applications in automobile parts, electrical and electronic parts as well as film, sheet, etc.
本发明公开了一种苯乙烯嵌段共聚物,其粘度降低至 0.01 至 20 dl/g (在 135°C 的 1,2,4-三氯苯中为 0.05 g/l in 1,2,4-trichlorobenzene at 135°C)的苯乙烯嵌段共聚物,它由高度齐聚的苯乙烯聚合物段和 10-⁴ 至 10 摩尔%的含杂原子的苯乙烯聚合物段组成;一种树脂组合物,它由上述苯乙烯嵌段共聚物和一种热塑性树脂、一种无机填料或一种有机填料组成;一种多层材料,其中至少一层由上述苯乙烯嵌段共聚物或上述树脂组合物构成;以及一种生产上述苯乙烯嵌段共聚物的工艺,该工艺包括在特定催化剂存在下聚合苯乙烯单体,并加入含杂原子的苯乙烯单体以连续进行共聚反应。上述苯乙烯嵌段共聚物和树脂组合物具有优异的相容性和粘合性,多层材料有望广泛应用于汽车部件、电子电气部件以及薄膜、板材等领域。

Design, synthesis and thermal behaviour of a series of well-defined clickable and triggerable sulfonate polymers
In the printing industry, the exploitation of triggerable materials that can have their surface properties altered on application of a post-deposition external stimulus has been crucial for the production of robust layers and patterns.
