Fuaiupu 1: O le faʻaaogaina sili ona taua o le phosphorus acid (faʻavae taʻimua acid) o le gaosiaina o le phosphonic phosphite, o se faʻamautuina i le PVC ma fesoʻotaʻiga chlorinated polymers. Fuaiupu 2: O le faʻaaogaina sili ona taua o le phosphoric acid (phosphoric acid) o le gaosiaina lea o le phosphite autu, o se faʻamautu i le PVC ma isi polymers chlorinated. Fesili: Pe tutusa le uiga o le fuaiupu 1 ma le fuaiupu 2? Ioe pe leai?
