WebThe structure of polymers containing long and straight chains falls into this category. PVC, i.e., polyvinyl chloride, is largely used for making pipes, and an electric cable is an example of a linear polymer. Branched-chain … WebAnother type of co-polymer is known as a graft co-polymer. An example is ABS. A is Acrylonitrile, the trivial name for propenonitrile. The backbone of the polymer is formed from phenylethene (styrene) and buta-1,3-diene. Propenonitrile (acrylonitrile) is added to the system and forms a grafted side chain onto the backbone.
