Title:
SILICON-CONTAINING CURABLE COMPOSITION, CURED PRODUCT OF THE SILICON-CONTAINING CURABLE COMPOSITION AND LEAD FRAME SUBSTRATE FORMED OF THE SILICON-CONTAINING CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2011/155459
Kind Code:
A1
Abstract:
A silicon-containing curable composition comprising: 100 parts by mass of a silicon-containing polymer with Mw of 3000 to 100,000, said silicon-containing polymer being obtained by hydrolyzing and condensing an organosilane mixture which comprises 5 to 50 mol% of R1SiX3, 0 to 50 mol% of R2SiX3, 0 to 40 mol% of R3R4SiX2 and 0 to 50 mol% of R5SiX3 and in which the sum of R2SiX3 and R3R4SiX2 is 5 to 60 mol%; 0 to 200 parts by mass of a prepolymer which is obtained by a hydrosilylation reaction between a copolymer of formula (2) and a compound of formula (3) or (3') and carries at least two Si-H groups per molecule; 0 to 30 parts by mass of a cyclic siloxane compound having at least two C-C double bonds, which are reactive with Si-H group, per molecule; 0.0001 to 10 parts by mass of an organic peroxide; 0 to 1.0 part by mass of a metal catalyst; and 10 to 1500 parts by mass of a filler. In formulae (2), (3) and (3'), R1 represents a C2-6 alkenyl group; R2 represents a C1-6 alkyl group; R3 and R4 represent a C1-6 alkyl group, etc.; R5 represents a phenyl group optionally substituted by a C1-6 alkyl group; X represents a C1-6 alkoxy group, etc., provided that at least one of R2 to R4 is a methyl group; R6 to R8 represent a C1-6 alkyl group, a phenyl group, etc.; f is from 2 to 10; g is from 0 to 8; and n is 1 or 2.
