Irabha ye-Styrene butadiene (SBR)
Incazelo Yomkhiqizo
Irabha ye-styrene butadiene: irabha yokwenziwa eyenziwe nge-copolymerization ye-styrene ne-butadiene. Ifomula yayo yamakhemikhali ingachazwa kanje: - (CH2-CH=CH-CH2) m - (CH-CH2) n -; Njengesinamathelisi sama-electrode, ithuthukisa amandla okusebenza kanye nokuzinza kwama-electrode.
Ulwazi Oluyisisekelo.
