Polymer characteristics
WebAddition polymerization leads to homo-chain polymers whereas condensation polymerization leads to hetero-chain polymers. The most important distinction is that in addition to polymers there is no loss of atom. However, in a condensation reaction, there is a loss of a molecule of water, ammonia, etc. as a by-product.
