ABS yog tsim los ntawm peb cov tshuaj monomers: acrylonitrile, butadiene, thiab styrene. Txhua lub monomer txhawb cov khoom sib txawv: acrylonitrile muab lub zog siab, thermal stability, thiab tshuaj lom neeg ruaj khov; butadiene muaj toughness thiab cuam tshuam tsis kam; thiab styrene ua kom yooj yim ntawm kev ua, siab - zoo nto tiav, thiab siab zog.
Raws li txoj cai, ABS yog cov khoom siv amorphous. Lub polymerization ntawm peb cov monomers yields ob -theem terpolymer uas muaj cov styrene txuas ntxiv -acrylonitrile theem thiab ib theem dispersed polybutadiene roj hmab. Cov khoom ntawm ABS yog nyob ntawm qhov sib piv ntawm peb lub monomers thiab cov qauv molecular hauv ob theem. Qhov no tso cai rau kev hloov pauv zoo hauv cov khoom tsim, uas ua rau muaj ntau pua qib sib txawv ntawm ABS ntawm lub khw. Cov qib sib txawv no muaj ntau yam ntawm cov yam ntxwv, xws li qib sib txawv ntawm kev cuam tshuam (los ntawm nruab nrab mus rau siab), nto tiav (los ntawm qis mus rau siab gloss), thiab kub distortion kuj. ABS cov ntaub ntawv yog cov yam ntxwv tshwj xeeb ntawm kev ua tau zoo, kev zoo nkauj zoo nkauj, tsis tshua muaj kev nkag siab, kev ruaj ntseg zoo, thiab lub zog muaj zog.
