摘要：
Styrene copolymer sizing agents in paper are determined by pyrolysis gas chromatography. Styrene monomer derived from the styrene sequences in the copolymer is used as the key product in the pyrograms of paper samples. The amounts of the sizing agents retained in paper samples are determined with a precision of about 1.4% relative standard deviation. The results obtained suggest that about 80% of the sizing agents added in the-pulp slurry ape retained in the paper samples studied. Furthermore, the amounts of the sizing agents in paper are interpreted in terms of the degree of sizing.
