Polimérisasi adisi ngawengku numbukeun molekul-molekul nu mibanda [[beungkeut kimia]] rangkep dua atawa tilu. ''Monomér'' (molekul idéntik nu nyusun polimér) nu teu jenuh ieu mibanda kaleuwihan beungkeut internal nu bisa dipegatkeun sarta ditumbukeun jeung monomér séjén pikeun ngawangun ranté ulangan. Polimérisasi adisi dilarapkeun kana produksi polimér kayaning poliéténa, [[polipropilén]], jeung [[polivinilklorida]] (PVC). A special case of addition polymerization leads to [[living polymerization]].
 
Polimérisasi kondensasi lumangsung nalika monomér kabungkeut ngaliwatan [[réaksi kondensasi]]. Réaksi ieu bisa dihasilkeun ku jalan metakeun molekul-molekul nu ngandung gugus fungsi [[alkohol]], [[amina]], atawa [[asam karboxilat]] (atawa turunan karboxil séjénna). Nalika amina meta jeung asam karboxilat, bakal kawangun [[amida]] atawa beungkeut péptida, kalawan ngaleupaskeun cai (jadina polimérisasi ''kondensasi''). Nya ku prosés ieu asam-asam amino numbu sarta ngagabung jadi protéin, sakumaha dijieunna kevlar.
Condensation polymerization occurs when monomers bond together through [[condensation reaction]]s. Typically these reactions can be achieved through reacting molecules incorporating [[alcohol]], [[amine]] or [[carboxylic acid]] (or other carboxyl derivative) functional groups. When an amine reacts with a carboxylic acid an [[amide]] or peptide bond is formed, with the release of water (hence ''condensation'' polymerization.) This is the process through which amino acids link up to form proteins, as well as how kevlar is formed.
 
The chain growth-step growth system categorizes polymers based on their mechanism. While most polymers will fall into their similar category from the addition-condensation method of categorization, there are a few exceptions.
