  摘要：

  1,3-Dioxolanes were synthesized by reactions of 3-cyclohexenecarboxaldehyde and 5-norbornene2-endo-carboxaldehyde with 1,2-ethanedithiol and 3-(2-propenyloxy)- and 3-propoxy-1,2-propanediols, as well as of propionaldehyde, benzaldehyde, and trichloroacetaldehyde with the latter two thiols. Dichlorocarbene addition, bromination, and epoxidation of the ring C=C were accomplished, and activity of the resulting products as dienophiles in Dield-Alder reactions was assessed.

  2-bromoalk-1-enes and alkynes were achieved in good yields by dehydrobromination of vicinal dibromides with tetrabutylammonium fluoride. Neighboring O-functional-group participation is important in determining elimination reactivity. tetrabutylammonium fluoride - elimination - 2-bromo­alk-1-enes - alkynes - vicinal dibromides

  A modified polyacetal is obtainable by heating 0.1 to 30 parts by weight of (B) a polymerizable compound having a modifying group such as an epoxy group, a carboxyl group or an acid anhydride group relative to 100 parts by weight of (A) a base polyacetal and introducing the modifying group of the polymerizable compound to the base polyacetal. The base polyacetal (A) includes (A1) a polyacetal selected from polyoxymethylene homopolymers and copolymers, and (A2) a polymerizable polyacetal having a functional group comprising a polymerizablly unsaturated bond. The introduction efficiency of the modifying group can be enhanced by adding 0.01 to 2.5 parts by weight of (C) a free-radical initiator relative to 100 parts by weight of the total amount of the components (A) and (B), and mixing the resultant mixture under a molten state of the polyacetal. According to such method, the affinity of the polyacetal is improved by introducing the modifying group to the base polyacetal with ease and high efficiency.

  通过加热 0.1 至 30 重量份的(B)具有改性基团（如环氧基、羧基或酸酐基）的可聚合 化合物（相对于 100 重量份的(A)基础聚缩醛），并将可聚合化合物的改性基团引入基 础聚缩醛，可获得改性聚缩醛。基础聚缩醛(A)包括(A1)选自聚氧乙烯醚均聚物和共聚物的聚缩醛，和(A2)具有包含聚合不饱和键的官能团的可聚合聚缩醛。通过添加 0.01 至 2.5 重量份的 (C) 自由基引发剂（相对于 100 重量份的 (A) 和 (B) 组分总量），并在聚缩醛熔融状态下混合所得混合物，可提高改性基团的引入效率。根据这种方法，通过将改性基团轻松、高效地引入基础聚缩醛中，聚缩醛的亲和性得到了改善。

  A resin composition comprises (1) a thermoplastic resin and (2) a modified polyacetal wherein a residue of a polymerizable compound having a functional group such as an epoxy group, a carboxyl group, an acid anhydride group or others is introduced to a base polyacetal in a proportion of 0.1 to 30% by weight relative to the base polyacetal. The thermoplastic resin includes various polymers such as an olefinic polymer, a styrenic polymer, a polyester, a polyamide and so on. The thermoplastic resins can be used singly or in combination, and the latter combination includes a combination of two or more species of resins being immiscible with each other, a combination of a polyacetal and a resin except for a polyacetal (e.g. an elastomer, etc.) and other combinations. The relative ratio of (1) the thermoplastic resin to (2) the modified polyacetal is such that the former/the latter equals about 1/99 through 99/1 (by weight).
