homopolymer

Japanese: homopolymer
homopolymer

…In the polymers produced by copolymerization, there are structural units derived from the raw monomers. Therefore, the properties of a copolymer are different from those of a polymer made from each single monomer (a homopolymer) and from their mixtures. In this way, copolymerization is carried out for the purpose of improving the properties of a polymer or synthesizing a polymer with completely new properties. …

From [Polymer]

…For example, by copolymerizing two types of monomers A and B in an addition polymerization reaction, a polymer compound is produced in which the structural units from A and B are contained in the same molecule. This compound has different properties from a polymer compound (homopolymer) made only of monomer A or only of monomer B. For this reason, copolymerization reactions are often used to improve the properties of a certain polymer. …

[Polymer]

…A polymer that has structural units based on two or more types of monomers in its molecules, such as ethylene and propylene, is called a copolymer. In contrast, a polymer that consists of structural units of only one type of monomer is called a homopolymer. Polymers made of high polymers are widely used as structural materials for fibers, plastics, rubber, etc. …

…共重合によって生成する高分子の中には,原料のモノマーに由来する構造単位が存在する。したがって共重合体の性質は,それぞれの単一モノマーだけからの高分子(単独重合体,ホモポリマーhomopolymer)とも,またそれらの混合物とも異なっている。このように共重合は,ある高分子の性質を改良したり,まったく新しい性質をもった高分子を合成する目的で行われる。…

【高分子】より

…たとえば付加重合反応において2種のモノマーAとBを共重合させることによって,Aからの構造単位とBからの構造単位が同じ分子に含まれた高分子化合物が生成する。この化合物は,モノマーAのみ,あるいはモノマーBのみからなる高分子化合物(単独重合体,ホモポリマーhomopolymer)とは異なる性質をもっている。このため,共重合反応は,あるポリマーの性質を改良するのにしばしば用いられる。…

【ポリマー】より

…エチレンとプロピレンのように2種類あるいはそれ以上のモノマーにもとづく構造単位を分子の中にもつポリマーをコポリマーcopolymer(共重合体)という。これに対して,1種類のモノマーの構造単位のみから成るポリマーをホモポリマーhomopolymer(単独重合体)という。高重合体から成る高分子物質は,繊維,プラスチック,ゴムなどの構造形成材料として,ひろく利用されている。…
