Nke mbụ, copolymer a nwere ezigbo ihe na-emepụta ihe nkiri.Ọ nwere ike ịmepụta ihe nkiri doro anya nke nwere ezigbo adhesion na ogologo oge.Nke a na-eme ka ọ bụrụ ihe dị mma maka mkpuchi na ntanye eji eme ihe dị iche iche gụnyere agba, varnishes na varnishes.
Na mgbakwunye, vinylpyrrolidone-vinyl acetate copolymers na-egosipụta ọmarịcha solubility na mmiri na ọtụtụ ihe mgbaze organic.Solubility a na-enye ya ohere iji ya dị ka ihe na-eme ka ọ dị arọ n'ụdị dị iche iche, gụnyere ngwaahịa nlekọta onwe onye dị ka gels ntutu, sprays na lotions.Ngwongwo nrapado mara mma nke copolymer a na-emekwa ka ọ bụrụ ihe bara uru n'ichepụta mbadamba nkume na capsules maka ụlọ ọrụ ọgwụ.
Tụkwasị na nke a, enwere ike gbanwee conductivity nke vinylpyrrolidone-vinyl acetate copolymers dị ka ihe ndị a chọrọ, na-eme ka ha dị mma maka ngwa eletriki na mkpuchi mkpuchi.Ndakọrịta ya na ihe dị iche iche dị ka ọla, plastik na textiles na-agbakwunye na ike ya na uru ya.
Tụkwasị na nke ahụ, vinylpyrrolidone-vinyl acetate copolymers bụ ihe na-ekpo ọkụ ma na-eguzogide radieshon UV, na-eme ka ọ dị ogologo ndụ na ịrụ ọrụ ogologo oge maka ngwa n'èzí.Nke a na-eme ka ọ bụrụ nhọrọ magburu onwe ya maka mkpuchi nchebe na ụlọ, ụgbọ ala na ngwá electronic.
Na nchịkọta, vinylpyrrolidone-vinyl acetate copolymers nwere ọmarịcha ihe na-emepụta ihe nkiri, solubility, conductivity electric, and thermal nkwụsi ike, na-enye ọtụtụ ohere maka ụlọ ọrụ dị iche iche.Ngwa ya sitere na mkpuchi na nrapado na ngwaahịa nlekọta onwe onye yana ngwa eletrọnịkị.Anyị nwere obi ike na vinylpyrrolidone-vinyl acetate copolymers ga-ezute ma gafere ihe ị tụrụ anya ya site na ịdị elu ha na arụmọrụ na-agbanwe agbanwe.
