    摘要： A process for the preparation of low-solvent alkyl diketenes of the general formula: ##STR1## in which R.sup.1 denotes C.sub.10 -C.sub.30 alkyl or C.sub.10 -C.sub.30 alkenyl and R.sup.2 denotes hydrogen or C.sub.1 -C.sub.8 alkyl, by causing carboxylic chlorides of the formula II ##STR2## in which R.sup.1 and R.sup.2 have the aforementioned meanings, to react with tertiary amines of the formula III ##STR3## in which R.sup.3, R.sup.4, R.sup.5 denote C.sub.1 -C.sub.12 alkyl or C.sub.3 -C.sub.12 cycloalkyl and R.sup.3 and R.sup.4 together denote a C.sub.2 -C.sub.11 alkylene dichain optionally interrupted by oxygen or nitrogen, in a substantially water-immiscible, inert solvent, wherein distillation is carried out at temperatures ranging from 80.degree. to 130.degree. C. and pressures ranging from 10 to 500 mbar and subsequently with the addition of water or steam.

    摘要： Composite materials comprising at least one natural fiber, at least one thermoplastic polymer, and at least one random copolymer having a molar mass Mn of up to 20,000 g/mol. The random copolymer is produced from the copolymerization of ethylene and at least one comonomer. The comonomer is selected from the group consisting of ethylenically unsaturated C3-C10 monocarboxylic acids; ethylenically unsaturated C4-C10 dicarboxylic acids or their anhydrides; epoxy esters of ethylenically unsaturated C3-C10 monocarboxylic acids, and (b4) comonomers of the general formula I: wherein R1 and R2 are a hydrogen or an unbranched or branched C1-C10-alkyl; R3 is identical or different and is a hydrogen, unbranched and branched C1-C10-alkyl or C3-C12-cycloalkyl, where two radicals R3 may be bonded together to form a 3-10-membered ring; X is an oxygen, sulfur or N—R4; R4 is an unbranched or branched C1-C10-alkyl; and A1 is a divalent group selected from C1-C10-alkylene, C4-C10-cycyloalkylene, and phenylene.
