Catalyst for disproportionation reaction of chlorosilane is prepared from silicon compd. substituted with ammonium salt (I) by bonding to inorganic compd. e.g., silica or zeolite or by mixing with (II) having formula R4(CH2)nSiX'3, hydrolysis, and polymerization; where n = 1 - 4; R = C1-4 alkyl; R1, R2 = C1-8 alkyl or aryl; R3 = C1-20 alkyl or alkyl having dimethyl amino gp.; X = Cl, Br, or I; R4 = C1-6 alkyl or aryl, -H, -SH, -CN, -NR52, or -O-CO-C (CH3)=CH2; R5 = C1-4 alkyl; X1 = Cl, Br, I, or OR6 gp.; and R6 = C1-4 alkyl. |
