DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Phosphonate-modified polysiloxanes prepd. by reacting of phosphonate-group-contg. silanes alone or with alkoxysilanes and water are useful as additives (esp. as antistatic additives) in elastomeres (esp. in siloxane elastomers). Thus, a polymer prepd. by hydrolytic polymn. 2212-11-5 and 5926-26-1 are cas registry numbers of chemicals which are used as reagents here. of a mixt. 12 g of dimethyldimethoxysilane and 25.6 g of di-Et ester of [(dimethoxymethylsilyl)methyl]phosphonic acid with 14.5 g of water and 3 wt.% of HCl at 80° and 100 mbar (44 wt.% of a cyclic part having mol. wt. 650 and 56 wt.% of a linear part having mol. wt. 6,200) is useful as an antistatic additive in a mixt. with a moisture-crosslinkable silicone (Elastosil). .
