R-C-4989 PEO136-PAA72 Na Whether in acidic or alkaline conditions, PAA-PEO can maintain its comb like structure. Due to the frequent grafting of comb like PEO branches onto the comb back PAA main chain, these comb like branches control the configuration changes of the dispersant in aqueous solution, resulting in a strong steric hindrance effect. price>
