The -Si-O-C-bond-linked copolymer prepared with acid as a catalyst is easy to be hydrolyzed and has poor performance. Assuming the presence of amine buffers, storage can be suspended for a long time. But because of its low price, the expansion potential is extremely obvious.
Broadly speaking, all additives that can resist the impact of rigid polymer products are collectively referred to as impact modifiers. The impact modifier in the sense is basically based on the theory of elastic toughening, and the compounds involved almost without exception belong to various copolymers and other polymers with elastic toughening effect. Take rigid PVC products as an example. Nowadays, the widely used varieties in the application market mainly include chlorinated polyCPE, ester copolymer ACR, ester-butadiene-benzene copolymer MBS, -based acetate copolymer EVA and -butadiene -Benzene copolymer ABS, etc. The EPDM used in the toughening modification of polypropylene also belongs to the scope of rubber toughening. After the 1980s, a theory of inorganic rigid particles toughened polymers came into being, and the rapid development of nanotechnology gave new meanings to plastic toughening modification and impact modifiers. In this regard, a large number of monographs and documents have been reported at home and abroad.

Various alkalis can remove graphite impurities. The stronger the alkali, the better the purification effect. The alkaline acid method mostly uses NaOH, which has a small melting point and strong alkalinity. The acid used in acid leaching can be HCl, H2SO4, HNO3 or a mixture of them. Among them, HCl is more used.
Baking soda is white crystals, soluble in water, and the aqueous solution is weakly alkaline.
