The polyether chain is based on ethylene oxide (EO) and propylene oxide (PO) units with a molar ratio of EO : PO approx. 4 : 1.
Genamin M41/2000 has an average molecular weight of approximately 2000 g/mol.
- very good soluble in cold or hot water and in many organic solvents like isopropanol or acetone
- slowly absorbs carbon dioxide from air and water from humid air
- the amino group reacts faster and forms more stable compounds than the hydroxyl group of the corresponding polyether alcohol
Genamin M41/2000 shows chemical reactions typical for primary amines like formation of:
- ammonium salts (pH dependent) with inorganic or organic acids,
- amides with carboxylic acids, anhydrides or esters,
- urea derivatives with isocyanates uncatalyzed at room temperature,
- aminoalcohols with epoxides,
- imines with aldehydes or ketones.
ApplicationsBased on the chemical and physical characteristics Genamin M41/2000 can be used in many fields of application like:
- Monofunctional chemical intermediate and hydrophilic macromonomer for end-capping.
- Synthesis of comb polymers with flexible polyether side-chains linked for example by amide groups to the back bone.
- Formulation of emulsifiers or synthesis of emulsifiers and dispersants.
- Raw material for superplasticizer in concrete.
- Pigment modification.
- Reactive building block in adhesives.
- Corrosion inhibitor with low vapour pressure.
