Polyvinyl doro (PVOH, PVA, kana PVAl) mukuvaka

Polyvinyl doro (PVOH, PVA, kana PVAl) imvura-inonyungudika yakagadzirwa polymer. Iyo ine yakasarudzika formula [CH2CH(OH)]n. Inoshandiswa mukugadzira mapepa, Glue, uye akasiyana machira.
Polyvinyl doro haina muchetura, biodegradable polymer, uye zvigadzirwa zvine PVA zvakachengeteka kushandisa uye zvakachengeteka kudyiwa. Sangano reEnvironment Working Group rakazvitemesa sechinhu chakaderera-chengozi muzvizoro, uye Food and Drug Administration yakabvumidza PVA kuti ishandiswe mukurongedza chikafu nemishonga yemishonga.
