摘要
An aerosol spray composition comprises by weight 10 to 30% of solvent, 69 to 89% of propellant and from 0.01 to 1% of a biologically active polymer of the formula R3SnO.OC.R1 in which R is a lower alkyl or phenyl radical and R1 is a polymerizable vinyl, a -methyl vinyl, or vinylphenyl radical. In an example an aerosol spray composition suitable for treating materials to render them resistant to attack by bacteria, fungi, mildew, mould and marine organisms comprises poly-(tri-n-propyltin methacrylate), toluene, isopropanol, and dichlorodifluoromethane.ALSO:A composition for protecting materials against fouling, e.g when immersed in sea water, includes as its active constituent a biologically active polymer of a compound R3SnO. OC.R' in which R is a lower alkyl or phenyl radical, and in which R' is a polymerizable vinyl, a -methylvinyl, or vinylphenyl group. The polymer may be applied in solution in an inert solvent or as a constituent of a paint.ALSO:Biologically active compositions include a polymer of a compound R3SnO.OC.R1 in which R is a lower alkyl or phenyl radical, and in which R1 is a polymerizable vinyl, a -methylvinyl, or vinylphenyl group. Homopolymers of tri-n-propyltin methacrylate, triphenyltin methacrylate, tri-n-butyltin p-vinylbenzoate, and tri-n-propyltin acrylate, and copolymers of tri-n-butyltin methacrylate with methyl methacrylate or with di-n-butyltin dimethacrylate are exemplified. Polymerization is effected in bulk, solution, emulsion or suspension, using free radical catalysts. The polymer is incorporated in a paint base, in an aerosol composition, or in a dustable or wettable powder, e.g. talc, limestone or diatomaceous earth.ALSO:Leather, seeds and plants are protected against attack by bacteria and fungi by treatment with compositions containing as active agents polymers of compounds R3SnO.OC.R1 in which R is a lower alkyl or phenyl radical, and in which R1 is a polymerizable vinyl, a -methylvinyl, or vinylphenyl group. The polymers are incorporated in paints, aerosol compositions, and solid or liquid inert diluents.ALSO:Materials are protected against the growth of pestiferous organisms, e.g. bacteria and fungi, by treating the material with a biologically active polymer of a compound R3SnO. OC.Rsv in which R is a lower alkyl or phenyl radical, and in which Rsv is a polymerizable vinyl, a -methylvinyl, or vinylphenyl group. The polymer is applied in a composition including as other ingredients paint bases, solid or liquid inert diluents, or aerosol compositions.
