WebJun 26, 2024 · A monomer is a type of molecule that has the ability to chemically bond with other molecules in a long chain; a polymer is a chain of an unspecified number of monomers. Essentially, monomers are the building blocks of polymers, which are more complex type of molecules. Monomers—repeating molecular units—are connected into … WebTable 1 Some addition polymers. In condensation polymerization, polymerization of one or more monomers is accompanied by the elimination of small molecules (such as water or ammonia) (Table 2).For example, in producing polyamide 6,6, two monomers are used. Another type of condensation polymer is said to be formed if the polymer chain contains …
WebPolymer processes for the production of plastics place high demands on the melt pump, which gently and efficiently transports the high- and low-viscosity plastic melts through the system. MAAG gear pumps enable oligomers and pre-polymers and the finished polymers (plastic melts) to be conveyed reliably in one flow, even at low filling levels ... WebMar 18, 2024 · To make the polymer known as nylon, diamine acid is forced to enter into a reaction with adipic acid. This type of polymer is commonly known as PA 6,6, and it was the first type of polymer to be used for nylon fabric. PA 6,6 is a type of substance called a nylon salt, and this crystallized substance is then heated to form a molten substance.
