查询词典 acrylic acid

The results showed that in the growth period of R. glutinosa, soil ferulic acid, vanillic acid, and vanillin contents had a persistent increase, while β-hydroxybenzoic acid content increased first but decreased then. The addition of ferulic acid (8 μg·ml-1), vanillic acid (08 μg·ml-1), vanillin (12 μg·ml-1), and β-hydroxybenzoic acid (30 μg·ml-1) in water culture had stronger inhibitory effects on R. glutinosa root length, root mass, fresh plant mass, and plant height. Treating with test phenolic acids except β-hydroxybenzoic acid increased leaf chlorophyll content significantly, compared with the control. After treated with test phenolic acids, plant SOD and POD activities decreased after an initial increase, and plant malondialdehyde content increased. In the treatment of ferulic acid, root SOD and POD activities were the lowest, and roots were rotted and dead.

The silicon-acrylic latices with core-shell structures were prepared by means of a"two-stage"emulsion copolymerization. The effect of constituents and proportion of core and shell parts on the properties of latex film were investigated, and their applications in water-borne wood coatings and elastic coatings were explored. The results indicate that wood coating and elastic silicon-acrylic coatings with good performance and zero VOC content can be prepared by suitable design of structure of silicon-acrylic latex particles.
