Claims26
A polymerizable system comprising:
- (a) an organoborane;
- (b) at least one polymerizable monomer;
- and
- (c) a work-life extending agent according to the general formula:
- 33
- wherein R40 is CH2=or alkenyl, Z1 and Z2 are independently O, N—R41 or S, and R41, R42 and R43 are independently H, alkyl, aryl or cycloalkyl, provided that when Z1 and Z2 are O, R42 and R43 are independently alkyl, aryl or cycloalkyl.
A polymerizable system comprising:
- (a) an organoborane;
- (b) at least one polymerizable monomer;
- and
- (c) at least 2.5 weight percent of itaconic acid, itaconic acid derivatives or combinations thereof.
A polymerizable system comprising
- (a) a first part comprising an organoborane;
- and
- (b) a second part comprising a polymerizable monomer;
- wherein at least one of the first part or the second part further comprises a work- life extending agent according to the general formula:
- 35
- wherein R40 is CH2=or alkenyl, Z1 and Z2 are independently O, N—R41 or S, and R41, R42 and R43 are independently H, alkyl, aryl or cycloalkyl, provided that when Z1 and Z2 are O, R42 and R43 are independently alkyl, aryl or cycloalkyl.
A polymerizable system comprising:
- (a) an organoborane;
- (b) at least one polymerizable monomer;
- and
- (c) about 8 weight percent itaconic di(butyl) ester.
A method of increasing the work-life of a polymerizable system comprising an organoborane and a polymerizable monomer, the method comprising adding itaconic acid, itaconic acid derivatives, or a combination thereof in an amount sufficient to provide an initial concentration of the itaconic acid, one of itaconic acid derivatives, or a combination thereof of at least 2.5 weight percent of the polymerizable system.
A polymerizable system comprising:
- (a) an organoborane;
- (b) a complexing agent comprising a material selected from amines, amidines, hydroxides, alkoxides, and combinations thereof;
- (c) at least one polymerizable monomer;
- and
- (d) a work-life extending agent according to the general formula:
- 36
- wherein R40 is CH2=or alkenyl, R42 is H or alkyl, R43 is H, and Z1 and Z2 are O and the ratio of amine-, amidine-, hydroxide- or alkoxide-reactive groups in the work-life extending agent to amine, amidine, hydroxide or alkoxide groups in the complexing agent(s) is over 3.0:1.0.
A polymerizable system comprising:
- (a) an organoborane;
- (b) at least one polymerizable monomer;
- and
- (c) a work-life extending agent according to the general formula:
- 37
- wherein R44 is CH2=or alkenyl and X is S or N—R50, where R50 is hydrogen, alkyl, aryl or cycloalkyl.
A polymerizable system comprising:
- (a) an organoborane;
- (b) a complexing agent comprising a material selected from amines, amidines, hydroxides, alkoxides, and combinations thereof;
- (c) at least one polymerizable monomer;
- and
- (d) a work-life extending agent according to the general formula:
- 38
- wherein R44 is CH2=or alkenyl and X is O and ratio of anhydride groups in the work-life extending agent to amine, amidine, hydroxide or alkoxide groups in the complexing agent(s) is over 3.0:1.0.
