Abstract:
A polymerizable composition comprising:a) at least one polymerizable monomer; b) an internally blocked borate having the structure (II) or (IIâ€²) wherein X represents â€”CHR7â€”, oxygen or sulfur; n is the integer 1, 2, 3, 4, or 5, and R1, R2, R3, R4, R5, R6 and R7 are independently selected from unsubstituted and substituted alkyl or alkylene groups containing 1 to 10 carbon atoms, substituted aryl groups having up to 7 to 12 carbon atoms, and unsubstituted aryl groups; alternatively either of R3, R4, R5, R6 and R7 are hydrogen; R1 and R2 alternatively are part of a second unsubstituted or substituted cyclic borate; R1 and R2 alternatively comprise a spiro ring or a spiro-ether ring; R1 or R2 together with R3 or R4 alternatively are linked to form a cycloaliphatic ring; and R1 or R2 together with either R3 or R4 alternatively comprise a cyclic ether ring; and M is any positively charged species with charge m greater than 0; andc) a compound that liberates an organoborane from said internally blocked borate.
