1. Polymers na sama suna nufin polymers waɗanda ƙananan monomers na ƙwayoyin halitta ko ƙananan polymers na ƙwayoyin halitta suka haɗa kansu ta hanyar hulɗar haɗin gwiwa mara haɗin gwiwa. Abubuwa kamar pH, zafin jiki da haske na iya haifar da rabuwa da sake tsara haɗin gwiwa mara haɗin gwiwa na polymers na supramolecular, waɗanda za a iya juyawa. Saboda haka, polymers na sama sune kayan fasaha waɗanda za a iya amfani da su azaman warkarwa da warkarwa kai tsaye. Ɗaya daga cikin wuraren bincike a cikin gida da ƙasashen waje a cikin 'yan shekarun nan. Polymers na sama suna da nau'ikan aikace-aikace iri-iri, kamar kayan fasaha da aka gyara, na'urorin lantarki da kayan halittu. A cikin 'yan shekarun nan, binciken da aka yi amfani da shi a fannoni na halittu da na halittu ya bunƙasa cikin sauri, gami da aikace-aikacen da suka shafi tantanin halitta, injiniyan nama, da sauransu.

Ana iya amfani da 1,3-bis(1-methylvinyl)benzene don shirya polymer mai ƙarfi kamar haka:

Sanya garin lipoic acid 10g a cikin wani reactor da aka sanya masa na'urar juyawa, a kunna mai har sai foda lipoic acid ya narke, sannan a fara juyawa. Sannan a zuba 6g (60wt%) 1,3-bis(1-methylvinyl)benzene (DIB) a cikin reactor, sannan a ci gaba da dumamawa da juyawa na tsawon mintuna 5. Sannan a zuba 0.1g na maganin ferric chloride acetone a cikin reactor, a ci gaba da dumamawa da juyawa na tsawon mintuna 3, a daina dumamawa, sannan a sanyaya zuwa zafin ɗaki don samun supramolecular polymer-1.

Ana iya amfani da 2.1,3-Di(1-methylvinyl)benzene don shirya hanyar gyara haɗin giciye ta resin musamman na polyvinyl chloride. Ƙarfin kayan polymer na PVC a cikin wannan hanyar ya dogara ne akan ƙarfin haɗin sinadarai da ƙwayoyin halitta akan babban sarkar. Ana amfani da rawar da haɗin valence na biyu ke takawa tsakanin nau'ikan wakilai 15 na haɗin giciye don shirya sabbin resins na musamman na PVC. Waɗannan wakilai masu haɗin giciye suna ɗauke da takamaiman ƙungiyoyi masu aiki, kamar haɗin biyu masu haɗin gwiwa, ƙungiyoyin phenyl, da ƙungiyoyin heterocyclic. Gabatar da waɗannan ƙungiyoyin Zai iya ƙara cikas ga sarkar kwayoyin polymer. A lokaci guda, ƙungiyoyin ionic da aka gabatar, ƙungiyoyin polar ko haɗin hydrogen da aka samar na iya inganta ƙarfin kayan polymer na PVC. Ta hanyar amfani da wakilin haɗin giciye tare da takamaiman tsari, wannan ƙirƙira yana gabatar da takamaiman tsarin haɗin giciye cikin sarkar macromolecular na PVC, yana canza shi daga tsarin layi zuwa tsarin hanyar sadarwa na gida. Wannan canjin tsari na iya ingantawa sosai. Juriyar zafi na PVC na iya rage raguwar zafi da inganta cikakken aikinsa, ta haka yana ƙara faɗaɗa yanayin aikace-aikacen PVC. Ta hanyar gyaran haɗin giciye, sarkar kwayoyin halitta ta polyvinyl chloride za a iya haɗa ta yadda ya kamata, ta yadda polymer ɗin zai sami cikakkun halaye na polyvinyl chloride da abubuwan da aka gyara. Waɗannan abubuwan haɗin giciye ba za a iya amfani da su kawai a cikin resin PVC mai yawan polymerization da matte ba. Ana amfani da su a cikin resin PVC. A lokaci guda, yana da yuwuwar amfani da su a cikin gyaran haɗin giciye na wasu resin PVC na musamman, kamar resin manna PVC, resin chlorine-vinegar, ƙarancin/ƙananan digiri na polymerization PVC, polyvinylidene chloride, CPVC, da sauransu.
