Classification of polymers based on chain / branch:
(1) Homo-chain polymer.
(2) Hetero-chain polymer.
(1) Homo-chain polymer:
Sulphur & Selenium have a high tendency to form homo-chain polymeric compounds. When sulphur is heated in the molten state the ring appears into a linear polymer.
(2) Hetero-chain polymer:
The polymeric Structure of hydrogen bond can be represented as silicon also as the branched polymer as -
Silicon also forms the branched polymer as-
