How are polymers classified on the basis of structure?

Answer 1

Polymers are synthesized from monomer units and are composed of thousands of repeating chain units. The length and branching of these chains will help to determine the structural properties of the polymer

Answer 2

On the basis of structure, polymers are classified as :

1. Linear polymers such as high density polythene (HDP), polyvinyl chloride, nylons, polyster, etc.
2. Branched polymers such as low density polythene (LDP), amylopectin, glycogen, etc.
3. Cross-linked polymers such as bakelite, melmac, (melamine-formaldehyde polymer), etc

On the basis of how they are formed they are either addition polymers, such as polythene, formed from monomers with multiple bonds, and condenstation polymers such as proteins, formed by the elimination of a small molecule between reactive groups.

Answer 3

Linear Polymers

These polymers are formed of long straight chains. Eg: HDP, Polyvinyl Chloride

Branched Chain Polymers

They are basically linear polymers with some branches. Eg: LDP, amylopectin

Cross Linked or Network Polymers

These polymers have may cross linking bonds that give rise to network like structure.These polymers contain Bi-Functional and tri-Functional monomers.

Answer 4

This question is extremely broad but simply polymers are constructed from monomers. The monomer units used, determine the structure/shape - simplified formula of a polymer. Taking the simplest example of all, ethylene can be polymerised to polyethylene. The structure could be simplified as shown below.

N (CH2=CH2 ) ----> ---[CH2-CH2-CH2CH2-CH2-CH2-]--N/3 this would show the structure was linear etc.

Answer 5

a polymer is made of many monomers in the process of polymerization

Answer 6

Polymers are formed in long, chainlike structures.

Answer 7

Polymers form when chemical bonds link large numbers of monomers in a repeating pattern

Answer 8

monomer
