WebNomenclature Rules for Polymers in China and How to Search Polymers on IECSC. Before searching IECSC, it is very important for a company to know the nomenclature rules in China. The Chinese name of a polymer should be named in accordance with . WebAn epoxide is a cyclic ether with three ring atoms. These rings approximately define an equilateral triangle, which makes it highly strained. The strained ring makes epoxides more reactive than other ethers. Simple epoxides are named from the parent compound ethylene oxide or oxirane, such as in chloromethyloxirane.
