ʻO ka resin synthetic he mea polymer, i hanaʻia ma ka huiʻana i nā mea haʻahaʻa molekala - monomers (e like me ka ethylene, propylene, vinyl chloride, a me nā mea'ē aʻe) i loko o nā macromolecules ma o ka polymerization.ʻO nā ʻano hana polymerization maʻamau i hoʻohana ʻia i ka ʻoihana e pili ana i ka polymerization nui, ka polymerization suspension, ka polymerization emulsion, ka polymerization solution, ka polymerization slurry, ka polymerization o ke kinoea, a me nā mea ʻē aʻe.I nā lā mua, ʻo ia ka nui o nā huahana koala a me ka calcium carbide calcium carbide.I kēia manawa, ʻoi aku ka nui o ka aila a me nā huahana kinoea maoli, e like me ka ethylene, propylene, benzene, formaldehyde a me ka urea.
