Kuberako ibikoresho bya PVC bitunganya bihuza cyane na PVC kandi bifite uburemere buringaniye bwa molekile (hafi (1-2) × 105-2.5 × 106g / mol) kandi nta fu yo gutwikira, ishobora gushyuha no kuvangwa mugihe cyo kubumba. Babanje koroshya no guhuza cyane ibice bikikije resin. Binyuze mu guterana no guhererekanya ubushyuhe, gushonga (gel) bitezwa imbere. Ubukonje bwo gushonga ntibugabanuka, cyangwa ngo bwiyongere; Bitewe no gufunga iminyururu ya molekile, ubworoherane, imbaraga, no kwaguka kwa PVC byatejwe imbere.
Mubyongeyeho, bitewe nuko ibice bihuye kandi bidahuye bya PVC bigize imfashanyo yo gutunganya hamwe na core-shell imiterere. Muri rusange, ntishobora kubangikanya na PVC bityo ikora nk'amavuta yo hanze, ariko ntigwa imvura kandi ikora umunzani, igira ingaruka zo gutinda gushonga. Kubwibyo, ukurikije ibyo biranga porogaramu, imfashanyo yo gutunganya PVC irashobora kugabanywamo ibyiciro bibiri: kwisi yose hamwe no gusiga. Igikorwa cyimfashanyigisho za PVC kwisi yose ni ukugabanya ubushyuhe bwo gushonga, kongera imbaraga zumuriro nuburinganire, kugabanya kuvunika gushonga, no gutanga ihindagurika ryinshi. Iyi mikorere ifite inyungu nini mugutunganya PVC: kugabanya ubushyuhe bwo gushonga bivuze kongera igihe cyumuriro wumuriro, gutanga umutekano mukoresha ibikoresho byakoreshejwe neza, no kwemerera gukomeza gutunganywa; Kunoza imbaraga zumuriro no kugabanya kuvunika gushonga, bivuze ko bishobora kongera umuvuduko wo gutunganya, kwihuta gukurura, kandi bikanazamura ubuziranenge bugaragara; Yateje imbere uburinganire bwashonga, bushobora kugabanya imivurungano yubuso no gushonga guturika kwibintu byakuwe hanze, bityo bikongera umusaruro, byongera ihindagurika hamwe nubushuhe.
