What is the difference between chemical monomer and elemental
The monomer is the basic unit that forms the polymer, usually the organic compound. Elemental is pure matter that contains only one element.
And the element is composed of the same element of pure matter. An element is called a free state of an element in the presence of an element. In general, the nature of the element is closely related to the nature of its element. For example, the metal properties of many metals are obvious, then their elemental reducibility is very strong. Different elements of the element, the nature of the differences reflected in the structure of the most prominent. In contrast to elemental matter, a substance consisting of multiple elements is called a compound
Select the monomer should consider the following factors; 1. Functional 2. Main chain chemical type: hydrocarbon type monomer, ether monomer, alkoxylated monomer. 3. Chemical structure: linear structure, branched structure, ring In general, the functionality is reduced, the viscosity decreases, the dilution capacity increases, the activity increases; the structure affects the viscosity and the homopolymer glass transition temperature; the molecular weight is low, the activity is large, the viscosity is low and the dilution ability is strong.
The chemical monomer is a low molecular weight compound used to synthesize the polymer, which is a diluent in UV, which belongs to a reactive diluent and is capable of participating in film formation and has a significant effect on the properties after curing.
