  Compositions are provided herein comprising a base material having engrafted polymer brushes. The polymer brushes further comprise one or more functional groups immobilized along the surface of the brushes in a plurality of layers, which confer functional properties to the base material compositions. Methods of using these compositions include deoxygenation of a sample solution, hydrolysis of denaturing agents in a sample solution, resolution of racemic mixtures in a sample solution, and purification, and concentration of target compounds.

  Compositions containing polyphenylene ether-poly(alkylene dicarboxylate) copolymers are prepared by a reaction between the two polymers and, optionally, at least one functionalizing agent therefor. The functionalizing agent may first be reacted with the polyphenylene ether and the resulting functionalized polyphenylene ether in turn reacted with a functionalized or unfunctionalized poly(alkylene dicarboxylate). Alternatively, an unfunctionalized or hydroxyalkyl-functionalized polyphenylene ether may be incorporated in a conventional polyester-forming reaction. The copolymer-containing compositions are characterized by a number of desirable properties including high impact strength and solvent resistance.

  含有聚苯醚-聚(亚烷基二甲酸酯)共聚物的组合物是通过两种聚合物和至少一种官能化剂的反应制备的。官能化剂可首先与聚苯醚反应，然后将得到的官能化聚苯醚与官能化或未官能化的聚(烷烃二羧酸盐)反应。或者，也可以将未官能化或羟烷基官能化的聚苯醚加入到传统的聚酯形成反应中。含共聚物的组合物具有许多理想的特性，包括高冲击强度和耐溶剂性。

  Functionalized polyphenylene ethers are prepared by reacting a polyphenylene ether with a polymerizable olefinic compound containing a phosphorus or silicon atom or an epoxy or lactam group, preferably in the presence of a free radical initiator. They may be used in the preparation of compatible polyphenylene ether blends with such polymers as polyesters and polyamides.

  官能化聚苯醚的制备方法是将聚苯醚与含有磷或硅原子或环氧或内酰胺基团的可聚合烯烃化合物反应，最好是在有自由基引发剂存在的情况下进行。 它们可用于制备与聚酯和聚酰胺等聚合物相容的聚苯醚混合物。

  Foamed articles of polyvinyl chloride resins are prepared by mixing an organic foaming agent having a temperature of foaming by decomposition of 100°C or above and a plasticizer with a polyvinyl chloride resin containing epoxy group which is formed into particles having an average diameter in the range from 0.05 to 5 µm and has a concentration of the epoxy group at the surface of the particle of 1×10⁻² weight % or more and a concentration of the total epoxy group in the particles of the said resin of 10 weight % or less at a temperature where the organic foaming agent does not decompose and coating or molding the mixed compound with foaming by heating. Foamed articles of polyvinyl chloride resins having excellent physical properties and high expansion ratios can be prepared without utilizing a crosslinking agent at the ambient pressure.
