Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
43 words
A liquid, curable epoxy composition comprised of a. an epoxy resin having more than one α-epoxy group in the molecule, b. a curing agent for said resin, and c. 4,4,4-trichloro-1,2-epoxybutane in a proportion which is sufficient to reduce the combustibility of said resin.
Claim 2
Dependent Claim
43 words
A liquid, curable epoxy composition comprised of a. an epoxy resin having more than one α-epoxy group in the molecule, b. a curing agent for said resin, and c. 4,4,4-trichloro-1,2-epoxybutane in a proportion which is sufficient to reduce the combustibility of said resin.
Claim 3
Dependent Claim
13 words
The composition of claim 1 wherein said epoxy resin is a glycidyl ether.
Claim 4
Dependent Claim
25 words
The composition of claim 2 wherein said proportion ranges from about 15 to about 250 parts per every 100 parts by weight of said resin.
Claim 5
Dependent Claim
41 words
The composition of claim 3 wherein resin is a glycidyl ether of a hydroxylated material selected from the group consisting of a bisphenol, a mononuclear dihydric phenol, a mononuclear trihydric phenol, a polynuclear phenol, an aliphatic polyol, and a novolac resin.
Claim 6
Dependent Claim
14 words
The composition of claim 4 wherein said resin is a glycidyl ether of bisphenol-A.
Claim 7
Dependent Claim
21 words
