inkcazelo
PolyTetrahydrofuran sisiqina esimhlophe esifana newax esinyibilika lula kwiialcohols, iiesters, iiketones, kunye ne-aromatic hydroICarbons kunye neehydrocarbons ezikhloriniweyo, kodwa azinyibiliki kwiihydrocarbons ze-aliphatic namanzi. Zijika zibe lulwelo olucacileyo xa ubushushu budlula ubushushu begumbi.
isicelo
I-Polytetrahydrofuran isetyenziswa ikakhulu njengenxalenye ethambileyo ye-polyurethane ecandiweyo okanye i-polyester ecandiweyo ye-polyester. I-rubber ye-polyurethane edibeneyo eyenziwe kwi-polytetrahydrofuran ene-avareji ye-molecular weight ye-1000 ingasetyenziselwa njengamatayara, amabhanti okuhambisa, i-gaskets, njl.; ingasetyenziselwa amalaphu, isikhumba sokwenziwa, iifilimu, njl njl. I-polyester ye-polyester edibeneyo eyenziwa yi-elastomer ye-thermoplastic. I-Polytetrahydrofuran ene-avareji yobunzima bemolekyuli ye-2000 ingasetyenziselwa ukwenza i-polyurethane elastic fibers.
