The effects of reaction time,heat transfer,mixing effects and solvents on a pilot plant and properties of product were studied during scaling up the process of the semi continuous bulk polymerization of impact resistant SMA in the pilot plant.

Development of impact propylene copolymer with high melt flowability;

Homogeneous design of experimentation was applied to gaseous copolymerization of ethylene-propylene over spherical Ziegler-Natta catalyst to prepare ethylene-propylene impact copolymer.

Flame-retardant ABS toughened by the impact modifier and CPE for specially-used engineering plastics was prepared from ABS757 matrix and BA-59P/Sb 2O 3 with the addition of the high-efficiently synergistic flame retardant system,and its retardant property was examined.

Methods The expression of integrin α5β1 and α-smooth muscle actin(α-SMA) in 30 resected restenosed human vein grafts(from Kerfuff clinical hospital of Germany) was detected by confocal immunofluorescence with specific antibodies against α5β1 and α-SMA.

Objective To study the influences of Ganxinning Decoction on protein expressions of α-smooth muscle actin(α-SMA),matrix metalloproteinase-13(MMP-13) and tissue inhibitor of metalloproteinase-1(TIMP-1) of liver tissue in rats with hepatic fibrosis.
