Cov catalyst siv hauv kev tsim khoom cuam tshuam rau hom khoom polybutadiene.
Hom polybutadiene muaj pes tsawg leeg los ntawm catalyst

Polybutadiene roj hmab (PBR)tuaj yeem muab faib ua ntau hom raws li nws cov txheej txheem microstructure thiab polymerization. Cov hom tseem ceeb muaj xws li siab cis polybutadiene, uas muaj cis -1,4 cov ntsiab lus saum toj no 95%, muab cov elasticity zoo heev thiab kev puas tsuaj, thiab qis cis polybutadiene, nrog qis cis -1,4 cov ntsiab lus, feem ntau siv rau hauv cov ntawv thov tshwj xeeb. Lwm cov kev hloov pauv muaj xws li cov yas polybutadiene siab, uas muaj qhov siab 1, 2-vinyl qauv rau kev txhim kho hardness thiab lub zog, thiab siab trans polybutadiene, uas muaj ib tug siab trans-1, 4 configuration, muab rigidity thiab dimensional stability. .
