Method for producing a thermodeformable polymer/fiber composite

A process for producing a thermoformable and/or -embossable fiber/polymer composite using a fibrous lignocellulosic substrate S and a polymer P, which contains

Fiber molding

A process for the preparation of 4-acetals of butene-1,4-dial of the formula ##STR1## where R is an alkyl, alkenyl, cycloalkyl or aralkyl radical of 1 to 12 carbon atoms which may contain alkoxy groups, or the two radicals R together form an alkylene or alkenylene radical of 2 to 10 carbon atoms which may contain alkoxy groups, and R.sup.1 is an alkyl, alkenyl or alkynyl radical of 1 to 12 carbon atoms which may be substituted by cycloaliphatic, aromatic or heterocyclic radicals or by hydroxyl, ether, thioether, acyl, alkylamino, carboxyl or carbalkoxy groups, or is an unsubstituted or substituted aryl radical or an alkoxy, alkylthio or acyloxy group, wherein a glyoxal monoacetal of the formula ##STR2## is reacted with an aldehyde of the formula

Motor fuel compositions contain alkoxylation products of oxo oils or their fractions or esters thereof, which are alkoxylated with propene oxide and/or butene oxides and/or not more than minor aomunts of ethene oxide.

Motor fuel compositions containing alkoxylation products

Cyclopentenones of the formula I ##STR1## where each of R.sup.1 to R.sup.4 is independently of the others hydrogen or an organic radical, are prepared by converting a carboxylic ester of the formula IIa, IIb or IIc
