Silicon is heated with methyl chloride at high temperature in the presence of Cu-powder at 570K, methyl substituted chlorosilaner MeSiCl3, Me,SiCl2,Me3‌SiCl and Me4‌Si are formed. After formation of Me2SiCl2,H2O is used for hydrolysis to form (CH1)2‌Si(OH)2 i.e. Q. Hence, Q is straight chain polymer
