Polymers structure
WebMany polymeric materials having chain-like structures similar to polyethylene are known. Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers.A listing of some important addition polymers and their monomer precursors is presented in the following … WebIn this article we will discuss about:- 1.

It has been … WebA polymer's molecular structure strongly affects crystallinity. If it's regular and orderly, highly symmetrical, it will pack into crystals more easily. In a way, the molecules want to get next to each other in crystalline domains. If the molecular structure is not highly regular and symmetrical, it won't.
WebPolymer types. There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength. WebIn this article we will discuss about:- 1.
