Isicelo

I-1.Isetshenziswa kakhulu njenge-polymerization inhibitor, i-UV inhibitor, udayi ophakathi nendawo kanye ne-antioxidant BHA yokuhlanganiswa kwamafutha adliwayo nezimonyo.
2. Isetshenziswa njenge-polymerization inhibitor, i-UV inhibitor, i-dayi ephakathi nendawo ne-antioxidant BHA (3-tert-butyl-4-hydroxyanisole) yokuhlanganiswa kwamafutha okudla nezimonyo.
3. Ncibilikisa. Isetshenziswa njenge-inhibitor ye-vinyl plastic monomer; I-Uv inhibitor; Udayi ophakathi nendawo kanye ne-antioxidant BHA (3-tert-butyl-4-hydroxyanisole) esetshenziswa ekuhlanganiseni kwamafutha adliwayo nezimonyo. Inzuzo yayo enkulu ukuthi i-monomer ngemuva kokwengeza i-MEHQ namanye ama-monomers ayidingi ukususwa lapho i-copolymerizing, ingaba i-copolymerization eqondile ye-ternary, futhi ingasetshenziswa njenge-antioxidant, i-antioxidant nokunye.
