| Abstract: | Study was conducted on preparation technology of super absorbent polymer by carboxymethylated Pinus radiata wood powder grafted by acrylic acid. Experiments were implemented for chemical component of wood powder, reaction conditions such as neutralization degree, monomer and initiator content. The best reaction condition was as follows: 60% of the neutralization degree of monomer, 8 ml/g of the monomer content, 0.04 g/g of initiator content. The prepared polymer was characterized by FTIR, and could absorb 6... |
