Asphalt yosinthidwa ya SBS imagwiritsa ntchito phula loyambira ngati zopangira, imawonjezera gawo lina la zosintha za SBS, ndipo imagwiritsa ntchito kumeta, kugwedeza ndi njira zina kufalitsa mofanana SBS muphula. Nthawi yomweyo, gawo lina la stabilizer yokhayokha limawonjezedwa kuti likhale losakanikirana la SBS. zinthu, kugwiritsa ntchito zinthu zabwino zakuthupi za SBS kusintha phula.
Kugwiritsa ntchito ma modifiers kusintha phula kuli ndi mbiri yakale padziko lonse lapansi. Pakatikati mwa zaka za m'ma 1800, njira ya vulcanization idagwiritsidwa ntchito kuchepetsa kulowa kwa phula ndikuwonjezera kufewetsa. Kukula kwa phula losinthidwa zaka 50 zapitazi kwadutsa pafupifupi magawo anayi.
(1) 1950-1960, sakanizani mwachindunji ufa wa rabara kapena latex mu phula, sakanizani mofanana ndikugwiritsa ntchito;
(2) Kuchokera ku 1960 mpaka 1970, mphira wopangidwa ndi styrene-butadiene anaphatikizidwa ndikugwiritsidwa ntchito pamalopo mwa mawonekedwe a latex molingana;
(3) Kuchokera mu 1971 mpaka 1988, kuwonjezera pa kupitirizabe kugwiritsira ntchito labala yopangira, utomoni wa thermoplastic unagwiritsidwa ntchito kwambiri;
(4) Kuyambira 1988, SBS pang'onopang'ono yakhala yotsogola yosinthidwa.
Mbiri yachidule yakukula kwa asphalt yosinthidwa ya SBS:
★Kupanga kotukuka kwa zinthu za SBS padziko lonse lapansi kudayamba cha m'ma 1960.
★Mu 1963, American Philips Petroleum Company inagwiritsa ntchito njira yolumikizirana kupanga mzere wa SBS copolymer kwa nthawi yoyamba, ndi dzina lamalonda la Solprene.
★Mu 1965, American Shell Company inagwiritsa ntchito ukadaulo wa ma ion polymerization ndi njira zitatu zotsatizana zodyetsera kuti apange chinthu chofanana ndi kukwaniritsa kupanga mafakitale, ndi dzina lamalonda la Kraton D.
★Mu 1967, kampani yaku Dutch Philips idapanga nyenyezi (kapena radial) mankhwala a SBS.
★Mu 1973, Philips adakhazikitsa nyenyezi ya SBS.
★Mu 1980, kampani ya Firestone inayambitsa malonda a SBS otchedwa Streon. Zomwe zimamangiriza zopangidwa ndi styrene zinali 43%. Chogulitsacho chinali ndi index yosungunuka kwambiri ndipo chimagwiritsidwa ntchito makamaka posintha pulasitiki ndi zomatira zotentha zosungunuka. Pambuyo pake, Kampani ya ku Japan ya Asahi Kasei, Kampani ya Anic yaku Italy, Petrochim Company ya ku Belgium, ndi zina zotero zinapanganso zinthu za SBS motsatizana.
★Atalowa m'zaka za m'ma 1990, ndikukula kosalekeza kwa malo ogwiritsira ntchito SBS, kupanga SBS padziko lonse lapansi kwakula mofulumira.
★Kuyambira m'chaka cha 1990, pamene malo opangira mphira a Baling Petrochemical Company ku Yueyang, m'chigawo cha Hunan anamanga chipangizo choyamba cha SBS chotulutsa matani 10,000 pachaka pogwiritsa ntchito ukadaulo wa Beijing Yanshan Petrochemical Company Research Institute, mphamvu yaku China ya SBS yakula kwambiri. .
