Graft copolymerization of vinyl monomers onto pulps(Part 1)

Vinyl 단양체의 펄프섬유에 대한 Graft중합(제1보)

Various monomers (Acrylonitrile, Vinyl acetate, Methyl methacrylate, Styrene) have been grafted onto cellulose pulps. Physical properties of the grafted pulps have heen studied and the results are: 1) increasing amount of water added to the pulp led to an increase in grafting yield, although above 30% water no further increase. 2) Increasing amount of grafted to the pulp A) led to an increase in diameter of fiber. B) led to a decrease in water sorption of the fiber. C) led to a decrease in density of the fiber. D) led to a decrease in the strength of single fiber. E) led to a decrease in beatability of the fiber.
