Abstract: Polymers used in sizing paper (see Division D2) are derived from imidazole derivatives having an ethylenically unsaturated polymerizable group on the ring nitrogen (monomer I), with or without one or more of the following comonomers: up to 95% by weight of one or more polymerizable unsaturated compounds containing in the molecule a carbonamido group with one or two substituents on the nitrogen atom (monomer II); up to 50% by weight of one or more further water-soluble monomers (monomer III); and up to 30% by weight of one or more water-insoluble monomers (monomer IV). Polymers referred to in the examples are: homopolymers of N-vinylimidazole (Examples 1-7, 9 and 10); binary copolymers of N-vinyl-imidazole with N-vinylcaprolactam (Examples 11(b) and (c), 12(a) and (b) and 14(b)), or N-vinyl-pyrrolidone (Example 13(e)), or acrylonitrile (Examples 13(a) and (c)), or acrylic acid (Example 13(b)), or ethyl acrylate (Example 16(a)); ternary copolymers of N-vinylimidazole with N-vinylpyrrolidone and N-vinylcaprolactam (Example 14(a)), or N-vinyl-pyrrolidone and acrylonitrile (Examples 11(a) and 13(d)), or dimethylacrylamide and acrylonitrile (Example 15), or N-vinylcaprolactam and vinyl acetate (Example 17); a ternary copolymer of butyl acrylate, acrylonitrile and vinylimidazole quaternized with dimethyl sulphate (Example 8); and a quaternary copolymer of N-vinylimidazole, N-vinylcaprolactam, N-vinylpyrrolidone and ethyl acrylate (Example 16 (b)). Specification 897,804 is referred to.ALSO:Paper is stock-sized or surface-sized with a water-soluble homopolymer or copolymer derived from one or more compounds of the type of imidazole having an ethylenically unsaturated polymerizable group on the ring nitrogen (monomer I). The copolymer may contain up to 95% by weight of one or more polymerizable unsaturated compounds containing in the molecule a carbonamido group with one or two substituents on the nitrogen atom (monomer II), or up to 50% by weight of one or more further water-soluble monomers (monomer III), or up to 30% by weight of one or more water-insoluble monomers (monomer IV). The Specification includes lists of suitable monomers. The paper may also be sized with rosin and alum, and may contain fillers, e.g. china clay. Specification 897,804 is referred to.

Abstract: Leather is simultaneously dyed and finished using a coloured polymer in which the dye is bound to the polymer by a covalent bond. The polymer may be obtained by copolymerizing a dye bearing at least one polymerizable olefinically unsaturated group with one or more polymerizable monomers (many listed) or the polymer may be one on to which a copolymerizable dye has been grafted or the polymer may be attached to the dye by way of reactive groups both on the polymer and the dye. The polymers may be in solution or dispersion, preferably aqueous dispersion. The coloured polymers may contain reactive groups, e.g. by using N-methylolacryl- or methacrylamide as a comonomer, through which cross-linking may be effected. The coloured polymers may be applied by brushing, dipping or spraying or in a drum. The so-treated leather may afterwards be glazed or plated. Examples are given. Specifications 877,402, 914,282, 946,472, 964,757 and 965,627 are referred to.
