Site na iwebata monomer copolymerization ya n'ime agbụ bụ isi nke vinyl chloride, a na-enweta polymer ọhụrụ nwere njikọ monomer abụọ, nke a na-akpọ copolymer.Isi ụdị na akụrụngwa nke copolymers nke vinyl chloride na monomers ndị ọzọ bụ ndị a:
(1) vinyl chloride vinyl acetate copolymer: mmeghe nke vinyl acetate monomer nwere ike ịrụ ọrụ nke plasticizer n'ozuzu, ya bụ, ihe a na-akpọ "plastisation n'ime ime", nke nwere ike izere evaporation, njem, mmịpụta na adịghị ike ndị ọzọ nke plasticizers n'ozuzu. , ma nwee ike ibelata viscosity na-agbaze, belata okpomọkụ nhazi ma melite arụmọrụ nhazi.N'ozuzu, ọdịnaya nke vinyl acetate na copolymer bụ 3 ~ 14%.
Ihe ọghọm dị na vinyl chloride vinyl acetate copolymer bụ mbelata ike tensile, okpomọkụ deformation okpomọkụ, iyi mkpuchi, nkwụsi ike kemịkalụ na nkwụsi ike ọkụ.
⑵ vinyl chloride vinylidene chloride copolymer: plasticization, nro na-ekpo ọkụ, solubility na intramolecular plasticization nke copolymer a bụ otu ihe ahụ na nke vinyl chloride vinyl acetate copolymer.A na-eji mmiri dị ala na nnyefe gas mara ya, nnukwu solubility na ketone solvents, na iguzogide dilution nke aromatics, ya mere enwere ike iji ya mee ihe nke ọma na mkpuchi.Na mgbakwunye, a na-ejikwa ya eme ihe nkiri na-ebelata.N'ihi nkwụsị ọkụ na-adịghị mma na nkwụsi ike ọkụ ma e jiri ya tụnyere vinyl chloride vinyl acetate copolymer, na ọnụ ahịa monomer dị elu, a naghị eji ya dị ka vinyl chloride vinyl acetate.
(3) vinyl chloride acrylate copolymer: mmetụta plasticizing dị n'ime nke copolymer a bụ nke vinyl chloride vinyl acetate, na-enwe ezigbo nkwụsi ike.Enwere ike iji ya rụpụta ngwaahịa siri ike na nke dị nro, ma melite usoro nhazi, nguzogide mmetụta na nguzogide oyi.Enwere ike iji ya maka mkpuchi, njikọta, wdg.
(4) vinyl chloride maleate copolymer: ọdịnaya nke maleate na copolymer a bụ ihe dị ka 15%, na mmetụta plasticizing dị n'ime ya yiri nke vinyl chloride acrylate.Ọ nwere ezigbo nhazi.Mbelata nke anụ ahụ na akụrụngwa dị ntakịrị, na nguzogide okpomọkụ dị elu karịa nke copolymers izugbe.
(5) vinyl chloride olefin copolymer: copolymerization nke ethylene, propylene na olefin monomers ndị ọzọ nwere ike ịmepụta resins copolymer na mmiri dị mma nke ọma, nkwụsi ike nke okpomọkụ, nkwụsị mmetụta, nghọta, nkwụsị ọkụ na ihe ndị ọzọ.
