The basic structural unit of yarn is the fiber . 纖維是紗的基本結構單元。
The majority of synthetic copolymers contain only two types of structural unit . 大多數(shù)的合成共聚物只有兩種形式的結構單元。
The simplest polymer which can be envisaged consists of the repetition of a single structural unit many times over to form a liner homopolymer . 可以想象,最簡單的聚合物是由一種結構物單元重復多次形成一個線型均聚物。
Clearly the principle requirement for a substance to be capable of forming a structural unit of a polymer chain is that it must be difunctional . 顯然,對于能成為聚合物鏈結構單元的物質(zhì)的基本要求是:它必須是雙官能的。
With many polymers the molecular weight of the structural unit is equal to the molecular weight of the monomer, e.g. with all vinyl monomers . 對許多聚合物,例如對所有的乙烯基單體的聚合物來說,結構單元的分子量等于單體的分子量。
In polymer chemistry, a structural unit is a building block of a polymer chain. It is the result of a monomer which has been polymerized into a long chain.
