Claims11
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:
- 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:
- 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:
- 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:
- 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.
