Hauv polymer chemistry, polymerization yog a txheej txheem ntawm reacting monomer molecules ua ke nyob rau hauv cov tshuaj tiv thaiv los tsim polymer chains los yog peb-dimensional tes hauj lwm. Muaj ntau hom ntawv polymerization thiab txawv systems muaj nyob rau categorize lawv.
Hais txog qhov no, cov kauj ruam ntawm polymerization yog dab tsi?
Cov polymerization cov tshuaj tiv thaiv muaj peb theem : (1) pib, (2) propagation, thiab (3) txiav. Kev pib tshwm sim thaum cov camphorquinones tau nce mus rau lub xeev dawb radical.
Ib tug kuj yuav nug, dab tsi yog tso rau hauv polymerization? Polymerization yog tus txheej txheem tsim polymers . Cov no polymers tom qab ntawd ua tiav los ua ntau yam khoom yas. Thaum polymerization , me me molecules, hu ua monomers los yog lub tsev blocks, yog chemically ua ke los tsim cov molecules loj los yog ib tug macromolecule.
Ib yam li ntawd, polymerization thiab piv txwv yog dab tsi?
Polymerization uas tshwm sim los ntawm kev sib txuas ntawm monomers siv lawv ntau daim ntawv cog lus yog hu ua ntxiv polymerization . Qhov yooj yim tshaj plaws piv txwv Kev tsim cov polyethylene los ntawm ethylene molecules. Polyethylene - zaj duab xis, ntim, fwj. Polypropylene - chav ua noj, fibers, khoom siv.
Polymerization txhais li cas?
1. polymerization - Cov txheej txheem tshuaj lom neeg uas sib xyaw ua ke ntau cov monomers los tsim cov polymer lossis polymeric compound. polymerization. Kev ua tshuaj lom neeg, tshuaj hloov pauv, cov txheej txheem tshuaj lom neeg - (chemistry) cov txheej txheem txiav txim siab los ntawm atomic thiab molecular muaj pes tsawg leeg thiab cov qauv ntawm cov tshuaj koom nrog.
