How is polymer formed
WebThis literally means a polymer is made from many monomer-repeating units. Polymers are larger molecules formed by covalently joining many monomer-units together in the form of chains like pearls on a string of pearls. The word plastic comes from 'plasticus' (Latin for ‘capable of moulding’) and 'plastikos' (Greek for ‘fit for moulding’). WebEverything you need to know about polymers!Polymers are large molecules made up of lots of repeating units called monomers. This video covers: how to identif...

WebA polymer network may also be formed by combining two different reactions. For example, a linear polymer end - capped with epoxy groups may be formed by reacting an excess of DGEBA with a monoamine. Alternatively, a branched polymer may be generated by reaction of an appropriate DGEBA excess with a diamine.
