WebAug 2, 2024 · SBS will absorb malthene and swell in the SBSMA, forming a polymer phase [32], [33]. SBS and asphaltene would compete for the solubility of the malthene phase. The phase separation will occur without enough malthene and the polymer phase will float up due to the low density [150]. WebFeb 15, 2016 · It can be seen that the area ratio of SBS-rich phase after phase separation for B4, B8, B12, B15 and B20 are 13%, 12%, 28%, 35% and 59%, respectively. The steep increase of area ratio of SBS-rich phase from B8 to B20 indicates the gradually decreased compositional asymmetry between SBS-rich phase. scott fawver https://pckitchen.net
