摘要:
A paper size comprising a water-soluble salt of a copolymer of from 30 to 85% by weight of olefins of 2 to 12 carbon atoms, having a terminal double bond, and/or vinyl ethers, and from 15 to 70% by weight of basic acrylic and/or methacrylic compounds, which copolymer has a molecular weight of from 600 to 4,500 and is manufactured by continuous copolymerization at from 130.degree. to 320.degree. C.
