6. Description of content:  This national standard applies to polydimethylsiloxane and 
aqueous emulsions (preparations) of polydimethylsiloxane. Polydimethylsiloxane consists of fully methylated linear siloxane polymers containing repeating units of the formula 
[(CH
3)2SiO] with trimethylsiloxy end-blocking units of the formula (CH 3)3SiO-. This 
additive is produced by hydrolysis of a mi xture of dimethyldichlorosilane and a small 
quantity of trimethylchlorosilane. The aque ous emulsions in commerce are produced by 
emulsifying polydimethylsiloxane with addi tion of water and necessary auxiliaries.
