Claims
- 1. A two-part initiator composition comprising:
- A) a stabilized organoboron amine complex of the formula: ##STR16## where R, R.sub.1 and R.sub.2 are alkyl of 1 to 10 carbon atoms or phenyl, R.sub.3 and R.sub.4 are hydrogen or alkyl of 1 to 10 carbon atoms, or ##STR17## where R.sub.5 and R.sub.6 are hydrogen or alkyl of 1 to 10 carbon atoms, m is 2 to 10 and n is 1 to 6, and
- B) an effective destabilizing amount of an aldehyde activator having the formula: ##STR18## where R is alkyl of 1 to 10 carbon atoms or aryl of 6 to 10 carbon atoms and x is 1 to 2.
- 2. The composition of claim 1 wherein in the organoboron amine complex, R, R.sub.1 and R.sub.2 are alkyl of 1 to 4 carbons, R.sub.3, R.sub.4 and R.sub.5 are hydrogen or alkyl of 1 to 4 carbon atoms, R.sub.6 is hydrogen, m is 2 to 6 and n is 1 to 2.
- 3. The composition of claim 2 wherein the R group of the aldehyde of Part B is an alkyl group of 1 to 4 carbons or an aryl of 6 to 8 carbons and x is 1.
- 4. The composition of claim 3 wherein the R group of the aldehyde is an aryl group and wherein from about 0.5:1 to 20:1 parts by weight of aldehyde to amine complex are used.
- 5. The composition of claim 4 wherein the second part B also contains a hydroperoxy compound.
- 6. The composition of claim 5 wherein the hydroperoxy compound has the formula R--OOH, where R is hydrogen, alkyl of 1 to 10 carbon atoms or aryl or alkaryl of 6 to 14 carbon atoms.
- 7. The composition of claim 5 wherein the complex is a combination of triethyl boron and ethylene diamine or propylene diamine.
