Abstract: A plastics compound includes a biological component, wherein at least (a) at least one biomineral filler and (b) at least one polymer are processed to give a compound. This is done using a renewable biomineral filler having a high proportion of silicon dioxide.

Abstract: A bio-material includes at least one thermoplastic, at least one biological filling material, and long glass fibres.

Abstract: The invention is directed to a composition containing from 45 to 99 weight percent of a permanent-magnetic and/or ferromagnetic metal-containing compound and from 1 to 55 weight percent of a polymer of formula IHO--?--CO--R.sub.1 --CO--X--Y--Z--!.sub.n --H (I)wherein R.sub.1 is phenyl, naphthyl, cyclohexyl, cyclohexenyl, or a C.sub.1 to C.sub.4 alkyl-substituted derivative thereof, and, if R.sub.1 is phenyl, the carboxy groups are in ortho, meta or para position to each other;X, Z are O or NR.sub.2, wherein R.sub.2 is H or C.sub.1 to C.sub.4 alkyl;Y is (CH.sub.2).sub.m or phenyl, cyclohexyl or cyclopentyl, and m is from 1 to 12; andn is an integer.Furthermore, the invention is directed to a process for producing said composition, a magnetic and a non-magnetic molded article made of said composition, the production of same and the use of said composition.
