Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
In an adhesive composition, which comprises, an elastomeric, polymeric resin and a tacifying proportion of a tackifier compound having a softening point greater than 35° C., the improvement which comprises; the presence of terpene ethers as tackifier ingredients, said terpene ethers being selected from those of the formula: (HO).sub.n-m R--(O--T).sub.n wherein T represents a terpene radical, R represents the residue of an alcohol or polyol after the removal of one or more hydroxyl groups and m and n are integers of 1 to 8 and n is ≧m; and wherein the terpene ethers have iodine values less than 20 and molecular greater than 300.
Claim 2
Dependent Claim
104 words
In an adhesive composition, which comprises, an elastomeric, polymeric resin and a tacifying proportion of a tackifier compound having a softening point greater than 35° C., the improvement which comprises; the presence of terpene ethers as tackifier ingredients, said terpene ethers being selected from those of the formula: (HO).sub.n-m R--(O--T).sub.n wherein T represents a terpene radical, R represents the residue of an alcohol or polyol after the removal of one or more hydroxyl groups and m and n are integers of 1 to 8 and n is ≧m; and wherein the terpene ethers have iodine values less than 20 and molecular greater than 300.
Claim 3
Dependent Claim
38 words
The composition of claim 1 wherein the elastomer is selected from the group comprised of styrene-butadiene copolymers, carboxylated styrene-butadiene polymers, styrene-isoprene-styrene copolymers, hydrogenated styrene-ethylene-butadiene styrene polymers, natural rubber of isoprene elastomers, ethylene vinyl acetate copolymers, and polyacrylate elastomers.
Claim 4
Dependent Claim
26 words
The composition of claim 1 wherein the terpene ethers are the acid catalyzed reaction products of a terpene and a mixture of an alcohol and polyol.
Claim 5
Dependent Claim
26 words
The composition of claim 1 wherein the terpene ethers are the acid catalyzed reaction products of a terpene and a mixture of an alcohol and polyols.
Claim 6
Dependent Claim
26 words
The composition of claim 1 wherein the terpene ethers are the acid catalyzed reaction products of a terpene and a mixture of alcohols and a polyol.
Claim 7
Dependent Claim
123 words
In an adhesive composition, which comprises an elastomeric, polymeric resin and a tackifying proportion of a tackifier compound having a softening point greater than 35° C., the improvement which comprises; the presence of terpene ethers as tackifier ingredients, said terpene ethers being selected from those of the formula: (HO).sub.n-m R(O--T).sub.n wherein T represents a terpene radical, R represents the residue of an alcohol or polyol after the removal of one or more hydroxyl groups and m and n are integers of 1 to 8 and n is ≧m; wherein the terpene ethers have iodine values less than 20 and molecular weights greater than 400; and wherein the terpene ether products are composed of the diadduct products of the reaction of trimethylolpropane and camphene.
