Total Claims: 7
Claim 1
Independent Claim
154 words
A thermosetting resin composition consisting essentially of (a) a butadiene-containing resin having an average molecular weight of 1000 to 5000 and being selected from the group consisting of acryloyloxyl- and methacryloyloxyl-terminated butadiene homopolymers and copolymers of butadiene with acrylonitrile or styrene which contain at least 70 weight percent of butadiene, said butadiene-containing resin having from 1.5 to 3.0 terminating acryloyloxyl or methacryloyloxyl groups per molecule of said butadiene-containing resin; (b) at least one ethylenically unsaturated monomer which is capable of copolymerizing with said terminating groups of said butadiene-containing resin and which is present in an amount between 50 and 200 weight percent based on said butadiene-containing resin; and (c) at least one unreacted ethylenically unsaturated acid anhydride selected from the group consisting of maleic anhydride, itaconic anhydride, dodecenyl succinic anhydride, methyl-endo-methylene-tetrahydrophthalic anhydride, tetrahydrophthalic anhydride and methyltetrahydrophthalic anhydride, and being present in an amount between 5 and 20 weight percent based on said butadiene-containing resin.
Claim 2
Dependent Claim
154 words
A thermosetting resin composition consisting essentially of (a) a butadiene-containing resin having an average molecular weight of 1000 to 5000 and being selected from the group consisting of acryloyloxyl- and methacryloyloxyl-terminated butadiene homopolymers and copolymers of butadiene with acrylonitrile or styrene which contain at least 70 weight percent of butadiene, said butadiene-containing resin having from 1.5 to 3.0 terminating acryloyloxyl or methacryloyloxyl groups per molecule of said butadiene-containing resin; (b) at least one ethylenically unsaturated monomer which is capable of copolymerizing with said terminating groups of said butadiene-containing resin and which is present in an amount between 50 and 200 weight percent based on said butadiene-containing resin; and (c) at least one unreacted ethylenically unsaturated acid anhydride selected from the group consisting of maleic anhydride, itaconic anhydride, dodecenyl succinic anhydride, methyl-endo-methylene-tetrahydrophthalic anhydride, tetrahydrophthalic anhydride and methyltetrahydrophthalic anhydride, and being present in an amount between 5 and 20 weight percent based on said butadiene-containing resin.
Claim 3
Dependent Claim
26 words
A thermosetting resin composition according to claim 1 in which said monomer is selected from the group consisting of styrene, divinyl-benzene, methyl-methacrylate, methyl-acrylate, glycidyl-methacrylate and ethylene-dimethacrylate.
Claim 4
Dependent Claim
21 words
A thermosetting resin composition according to claim 1 in which at least 70 weight percent of said butadiene-containing resin is 1,2-polybutadiene.
Claim 5
Dependent Claim
30 words
A thermosetting resin composition according to claim 1 further including a hardening agent in an amount between 0.1 and 2 weight percent based on the total weight of said composition.
Claim 6
Dependent Claim
35 words
A thermosetting resin composition according to claim 4 in which said hardening agent is a peroxide selected from the group consisting of benzoyl peroxide, lauroyl peroxide, dicumyl peroxide, methyl ethyl ketone peroxide and cumene hydroperoxide.
Claim 7
Dependent Claim
29 words
A thermosetting resin composition according to claim 4 in which said hardening agent is a photo-sensitizer selected from the group consisting of benzoin, benzophenone, benzoin ethyl ether and 2-methyl-anthraquinone.
