    摘要： Synthetic polymeric adsorbents are produced from lightly crosslinked macroreticular aromatic copolymer beads by post crosslinking the copolymer beads while in a swollen state, the crosslinks resulting from the post-crosslinking comprising the residue of external crosslinker selected from polyfunctional alkylating agent, polyfunctional acylating agent and sulfur halide. A Friedel-Crafts catalyst may be used for the post-crosslinking. The adsorbents may be functionalized to produce ion exchange resins. The adsorbents are generally useful in processes for removing components from fluids by adsorption, particularly in adsorbing organic components from liquid or gas streams. The ion exchange resins are useful not only in ion exchange processes in general but may also be useful as catalysts.

    摘要翻译： 合成的聚合物吸附剂由轻度交联的大网络芳族共聚物珠粒通过在膨胀状态下对共聚物珠进行后交联来制备，后交联产生的交联包括选自多官能烷基化剂，多官能酰化剂和卤化硫的外部交联剂的残余物 。 Friedel-Crafts催化剂可用于后交联。 吸附剂可以被官能化以产生离子交换树脂。 吸附剂通常可用于通过吸附从流体中除去组分的方法，特别是在从液体或气体流中吸附有机组分时。 离子交换树脂不仅用于一般的离子交换方法，而且可用作催化剂。

    摘要： High impact polystyrene resins are provided having a surprisingly good combination of toughness and gloss characteristics. Such resins contain small (i.e. 0.1 to 0.4 micron) capsule morphology rubber particles in combination with relatively small (i.e. 0,25 to 1 micron) entanglement morphology rubber particles. It has been found that such resins are capable of providing izod impact strength values in the range of 2.5 to 3.5 ft-lb/in (133.4 to 186.7 J/m) and higher at an overall volume average rubber size of less than 0.4 micron with corresponding gloss values in excess of 90 percent.

    摘要： Disclosed is a new styrenic copolymer comprising: (a) repeating styrene units of general formula (I), wherein R1 represents a hydrogen or halogen atom, or a hydrocarbon group having 20 or less carbon atoms and n is an integer of 1 to 3, provided that R1 groups may be the same or different from each other when n is 2 or 3, and (b) repeating olefin units of general formula (II), wherein R2 represents a hydrogen atom or a saturated hydrocarbon group having 20 or less carbon atoms, or (c) repeating diene units, wherein the proportion of the repeating olefin units (b) or diene units (c) is 0.1 to 99.9 % by weight. The copolymer has a limiting viscosity of 0.07 to 20 dl/g as measured in 1,2,4-trichlorobenzene at 135°C and the stereoregularity of the chain of the repeating styrene units is highly syndiotactic. It is excellent in the resistance to heat, chemicals and so forth and capable of low-temperature injection molding. It has also a good compatibility with other resins.
