New propene derivatives as intermediates for the preparation of pesticidal silane derivatives. Compounds of the formula ##STR1## wherein R.sup.4 is H, R.sup.5 is a radical of the formula ##STR2## and R.sup.17 is H or halogen are useful intermediates for the preparation of pesticidal silane derivatives.

In filler-containing plastic molding compositions based on polyoxymethylene, very good compatibility between the filler and the polymer matrix is obtained when alkali metal or alkaline earth metal salts of certain sulfonic acids or alkylsulfuric acids are used as adhesion promoters. The result is that in particular the flow properties of the molding compositions and mechanical properties of the plastic articles prepared therefrom as well as the color properties are improved.

In filler-containing molding compositions a very good compatibility between the hydrophilic filler and the hydrophobic polymer matrix is obtained by using as adhesion promotor alkali metal salts of alkyl or alkylene-sulfonic acids or alkyl sulfates, the derivatives thereof and the acids on which the salts are based. The flow properties of the molding compositions and the mechanical properties of the shaped articles made therefrom are improved.

Filler-containing molding composition and process for its manufacture

In the case of polyolefins filled with alkaline earth metal carbonates, a very good compatibility of the hydrophilic filler and the hydrophobic polymer matrix is reached when using as adhesion promoters certain organo-phosphorus compounds. As a result, improved mechanical properties are obtained with the articles made of plastic material that has been prepared from such polyolefin molding compositions.

Plastic molding composition containing a filler

Thermoplastic polymers are stabilized against ultra-violet radiation by incorporating therein as a stabilizer a stabilizing amount, e.g., 0.1 to 5% by weight of a tertiary phosphine oxide or sulfide of the general formula: ##EQU1## in which X is oxygen or sulfur and R.sub.1, R.sub.2 and R.sub.3 are each selected from hydroxyalkyl, haloalkyl, carbalkoxyalkyl, acyloxyalkyl, phenylhydroxyalkyl wherein the phenyl radical may be substituted by one or more halogens, and cyanoalkyl wherein the alkyl radical has 1 to 6 carbon atoms.
