Kedu ihe bụ Polymerization?

Polymerization bụ mmeghachi omume kemịkalụ nke ejikọtara monomers (obere ụmụ irighiri ihe) iji mepụta polymer (nnukwu molekul). Usoro a na-agụnye nguzobe nke njikọ covalent n'etiti monomers, na-ebute usoro dị ka yinye na nkeji ugboro ugboro.

Polymerization nwere ike ime site na usoro dị iche iche, gụnyere mgbakwunye polymerization na polymerization condensation. Na mgbakwunye na polymerization, monomers na-ejikọta ọnụ site na usoro mmeghachi omume kemịkalụ na-agbakwunye otu monomer n'otu oge na ụdọ polymer na-eto eto. Usoro a na-achọkarị ka a na-eji ihe na-akpali akpali iji malite mmeghachi omume. Ihe atụ nke polymer mgbakwunye gụnyere polyethylene, polypropylene, na polystyrene.

N'aka nke ọzọ, polymerization condensation na-agụnye mkpochapụ nke obere molekul, dị ka mmiri ma ọ bụ mmanya na-aba n'anya, dị ka monomers na-ejikọta na-emepụta polymer. Usoro a na-achọkarị ụdị monomers abụọ dị iche iche, nke ọ bụla nwere otu reactive nke nwere ike ịmepụta njikọ njikọ na nke ọzọ. Ihe atụ nke polymer condensation gụnyere naịlọn, polyester, na polyurethane.

A na-eji polymerization eme ihe n'ọtụtụ ngwa ngwa, gụnyere mmepụta nke plastik, eriri, nrapado, mkpuchi, na ihe ndị ọzọ. Enwere ike ịhazi njirimara nke polymer na-esi na ya pụta site n'ịgbanwe ụdị na ọnụọgụ nke monomers, yana ọnọdụ nke mmeghachi omume polymerization.
