Yog tias daim ntawv lo ntawm ib daim khaub ncaws hais tias "acrylic", ces nws yog ua los ntawm ib co copolymer ntawm polyacrylonitrile. Nws tau tsim rau hauv spun fiber ntau ntawm DuPont hauv xyoo 1942 thiab ua lag luam raws li lub npe ntawm Orlon . Acrylonitrile feem ntau ua hauj lwm raws li ib tug comonomer nrog styrene, e.g. acrylonitrile, styrene thiab acrylate plastics.

Kuj nug, yog Orlon yog polymer?

Orlon yog polymer ntawm vinyl cyanide nyob rau hauv cov nqe lus ntawm science. Yog li, nws yog tsim los ntawm kev sib ntxiv ntawm acryolnitrile molecules. Cov pa roj carbon ventral lov lawv ob daim ntawv cog lus los tsim ib daim ntawv cog lus tshiab ib qho tshiab ntxiv cov ntawv cog lus. Orlon yog ib hom khoom hluavtaws, acrylic textile fiber ntawm lub teeb yuag thiab wrinkle resistant ntaub.

Tsis tas li ntawd, PVC puas yog copolymer? PVC piv txwv li Poly vinyl chloride yog homopolymer raws li nws tau tsim los ntawm ib hom monomer piv txwv li vinyl chloride. Cov polymers uas nws rov ua dua yog muab los ntawm ob hom monomers hu ua copolymers . Piv txwv li, Buna-S yog a copolymer ntawm 1,3-butadiene thiab styrene.

Ntawm no, Teflon puas yog copolymer?

Cov polymers uas yog tsim los ntawm cov txheej txheem polymerization ntawm tib hom ntawm ib chav tsev monomer hu ua Homopolymers. Thaum cov polymers uas yog tsim los ntawm cov txheej txheem polymerization ntawm ob qhov sib txawv monomeric units yog hu ua Copolymers . HOMOPOLYMERS: PVC, polystyrene, neoprene, Teflon.

Dab tsi yog statistical copolymer?

Kev txheeb cais copolymer yog copolymers nyob rau hauv uas cov sequential faib ntawm cov monomeric units ua raws li paub txheeb cais txoj cai; Piv txwv li, qhov kev faib tawm monomer yuav ua raws li Markovian txheeb cais ntawm zeroth (Bernoullian), thawj, thib ob, lossis siab dua.
