  • Fire resistant polymer composition
    Patent number: 4035447
    Abstract: A fire resistant polymer composition comprising 99.9 to 50 parts by weight of a copolymer consisting essentially of 90 to 10 weight percent nuclear-halogenated aromatic vinyl compound, 10 to 90 weight percent cyanized vinyl compound, and 0 to 30 weight percent one or more monomers copolymerizable therewith; 0 to 20 parts by weight rubber-like polymer; and 0.1 to 30 parts by weight of a member selected from the group consisting of iron family compounds, tin compounds, and mixtures thereof.

  • Polymerizable emulsifying agent and application thereof
    Patent number: 3980622
    Abstract: Compounds having the formula ##EQU1## wherein R is alkyl group having 6 to 22 carbon atoms, M is H, Li, Na, K or NH.sub.4 and n is an integer of 2 to 4, inclusive. The compound is useful as polymerizable emulsifying agent, and enables to improve properties of produced polymer and to provide a modacrylic fiber superior in heat stability and fastness to light. The aqueous emulsion polymerization of .alpha.,.beta.-ethylenically unsaturated monomer by the use of the polymerizable anionic emulsifying agent is capable of preventing a discharge of an environmental pollutant.
