Patent number: 4360455Abstract: A mixture of brominated oligomeric polystyrenes, having a degree of polymerization of from 3 to 400, and low molecular weight brominated aromatic compounds of the diphenyl ether type is obtained by polymerizing the non-brominated starting materials, in a halohydrocarbon solvent, using a Lewis acid catalyst. The reaction mixture is then brominated and extracted with water to remove hydrogen bromide and catalyst, and the solvent and volatile constituents are separated from the product. The bromination is carried out at from -30.degree. C. to +130.degree. C. The final mixtures have a low melt viscosity and are therefore particularly suitable for incorporation, as a flameproofing agent, into thermoplastics.Type: GrantFiled: January 26, 1981Date of Patent: November 23, 1982Assignee: BASF AktiengesellschaftInventors: Gerhard Lindenschmidt, Wolfgang Schulte, Franz Brandstetter, Herbert Naarmann, Klaus Penzien

Patent number: 4286959Abstract: The invention seeks to provide a free-flowing formulation of one or more disperse dyes, with which packages can be dyed homogeneously by the HT process without filtering out of the dye, and which is suitable for the thermosol dyeing process. According to the invention such a formulation comprises one or more disperse dyes (a) enclosed in a matrix of one or more polymers (b) which are soluble, or colloidally soluble, both in water and in an organic solvent, in the form of a solid solution in a state of molecular dispersion or of extremely fine subdivision so that in an X-ray spectrum the dye appears amorphous.The formulations may contain additional assistants conventionally present when dyeing hydrophobic fibers. The formulations contain the disperse dye in an extremely fine state of subdivision. Because of the latter, the formulations give level package dyeings, without filtration of the dye, and very level dyeings when used by the thermofixing process.Type: GrantFiled: March 8, 1979Date of Patent: September 1, 1981Assignee: BASF AktiengesellschaftInventors: Dieter Horn, Ewald Daubach, Erwin Hahn, Herbert Uhrig, Richard Hoene, Herbert Naarmann

Patent number: 4205144Abstract: Graft copolymers comprising a crosslinked, saturated, elastomeric grafting base and a hard shell are prepared by incorporating thermolabile comonomers, as copolymerized units, into the grafting base during the preparation of the latter, in particular at a conversion of from 50 to 90%. During the subsequent grafting of the shell, the conditions used are such that the thermolabile comonomers incorporated as copolymerized units into the grafting base decompose into free radicals. This gives graft copolymers having improved mechanical properties, which copolymers also prove advantageous for the preparation of mixtures with other thermoplastics compatible with the graft copolymers.Type: GrantFiled: October 19, 1978Date of Patent: May 27, 1980Assignee: BASF AktiengesellschaftInventors: Herbert Naarmann, Graham E.
