This invention relates to organosiloxanes which have SiC-bonded ester groups and contain at least one unit of the general formula: ##EQU1## is which R represents the same or different monovalent hydrocarbon radicals having from 1 to 12 carbons atoms, which are free of aliphatic unsaturation and which may contain one ether oxygen atom; R' represents hydrogen or a methyl group (CH.sub.3) and a is O, 1 or 2. These organosiloxanes can be prepared by hydrolyzing or co-hydrolyzing silanes of the general formula:

Process for preparing methyltin chlorides

An improved method for preparing modified organopolysiloxanes which comprises graft polymerizing monomers containing aliphatic unsaturation onto organopolysiloxanes in the presence of a free radical and an inert liquid having a boiling point up to about 100.degree. C. at 760 mm Hg (abs.) and which is a nonsolvent for the organopolysiloxanes and the graft polymers at the applicable polymerization temperatures.

Method for preparing modified polysiloxanes

2,4,4-Trichlorobutadienyl-1-phosphate and 1-phosphonates are novel compounds, and are effective against organisms such as insects, acarides, and nematodes, and are suitable for application to plants.
