within PSA/Ca-MMT/CaCl2 @SiO2 was 10.91%.


The TEM photographs of graft copolymer and YSW-1 are shown in Figure 3. SiO2


had a strong influence on the morphology of graft polymer since


it was compactly deposited on graft polymer particle by particle from the photographs.

and B before and after aging tests. As shown in Table 1, the influence of SMA/CaCO3


Ca-MMT/CaCl2 @SiO2 and PSA/Ca-MMT/ on the rheological and filtration properties in Formulations A /CaCl2 @SiO2 and PSA/ on the rheological properties was minor, but the


effect on filtration properties was significant at room temperature, in contrast to Formulation A. The filtration loss of SMA/CaCO3 was approximately the same with PSA/Ca-MMT/CaCl2 temperature, a minimal amount of SiO2 CaCl2@SiO2 and SMA/CaCO3 reacted with Ca2+

loss was almost the same. After the thermal aging tests (200 ºC), the effect of SMA/CaCO3


SiO2 on the AV, PV, and YP was greater than PSA/Ca-MMT/CaCl2 /CaCl2 @SiO2 @SiO2 . At room
