Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 39 words
A silane end-capped polyarylene polyether of the formula: X--polyarylene polyether chain--X' wherein X and X' individually represent silane end groups, wherein each silane end group contains at least one hydrolyzable substituent group or at least one silanol hydroxyl group.
Claim 2
Dependent Claim 39 words
A silane end-capped polyarylene polyether of the formula: X--polyarylene polyether chain--X' wherein X and X' individually represent silane end groups, wherein each silane end group contains at least one hydrolyzable substituent group or at least one silanol hydroxyl group.
Claim 3
Dependent Claim 17 words
The silane end-capped polyarylene polyether of claim 1 wherein the hydrolyzable substituent is alkoxy, dialkylamino, or oxycarbonylalkyl.
Claim 4
Dependent Claim 27 words
The silane end-capped polyarylene polyether of claim 1 wherein said polyarylene polyether contains alkoxy, silanol hydroxy, or both, substituents on the silicon atoms of the silane groups.
Claim 5
Dependent Claim 121 words
The silane end-capped polyarylene polyether of claim 1 which is a composition of the formula: (R') 3 Si-R-O--Ar-O-- n R-Si(R') 3 wherein each R' individually represents alkyl, alkoxy, dialkylamino, or oxycarbonylalkyl substituent groups and at least one R' on each silicon atom represents a hydrolyzable group; wherein each R individually represents a divalent hydrocarbyl group bonded to the silicon atom with a direct carbon-to-carbon bond, and bonded to the oxy group through an aliphatic carbon atom; wherein n is a positive number; and wherein Ar represents a divalent aromatic group that can be the same or different from one --Ar-O-- group to the next, and in which each Ar group is bonded to the connecting oxy groups through aromatic carbon atoms.
Claim 6
Dependent Claim 17 words
The silane end-capped polyarylene polyether of claim 4 wherein each R individually represents alkylene, cycloalkylene, or aralkylene.
Claim 7
Dependent Claim 26 words
The silane end-capped polyarylene polyether of claim 4 wherein at least some of the hydrolyzable substituents on the silicon atoms have been replaced with hydroxy groups.
Claim 8
Dependent Claim 26 words
The silane end-capped polyarylene polyether of claim 5 wherein at least some of the hydrolyzable substituents on the silicon atoms have been replaced with hydroxy groups.
Claim 9
Dependent Claim 71 words
The silane end-capped polyarylene polyether of claim 4 which is a composition of the formula: (R') 3 Si-R-O-E--O-E'-O-E-- n O-R-Si(R') 3 wherein n, R, and R' have the meanings stated in claim 4; wherein E represents the residue after removal of the hydroxyl groups of a dihydric phenol; and wherein E' represents the residue after removal of the two activated halo groups of an aromatic compound having two activated halo substituents.
Claim 10
Dependent Claim 17 words
The silane end-capped polyarylene polyether of claim 8 wherein each R individually represents alkylene, cycloalkylene, or aralkylene.
Claim 11
Dependent Claim 26 words
The silane end-capped polyarylene polyether of claim 8 wherein at least some of the hydrolyzable substituents on the silicon atoms have been replaced with hydroxy groups.
Claim 12
Dependent Claim 26 words
The silane end-capped polyarylene polyether of claim 9 wherein at least some of the hydrolyzable substituents on the silicon atoms have been replaced with hydroxy groups.
Claim 13
Dependent Claim 33 words
The silane end-capped polyarylene polyether of claim 8 wherein E represents the residue of hydroquinone, 2,2-bis(4-hydroxyphenyl)propane, 4,4'-thiodiphenol, p,p'-biphenol, or bis(4-hydroxyphenyl) sulfone, and wherein E' represents the residue of 4,4'-dihalodiphenyl sulfone, 4,4'-dihalobenzophenone, or 4,4'-bis(4-halophenylsulfonyl)biphenyl.
Claim 14
Dependent Claim 24 words
the silane end-capped polyarylene polyether of claim 8 wherein E represents the residue of 2,2'-bis(4-hydroxyphenyl)propane, and wherein E' represents the residue of 4,4'-dihalodiphenyl sulfone.
Claim 15
Dependent Claim 20 words
The silane end-capped polyarylene polyether of claim 8 wherein R represents alkylene, and wherein the hydrolyzable R' groups are alkoxy.
Claim 16
Dependent Claim 22 words
The silane end-capped polyarylene polyether of claim 14 wherein at least some of the alkoxy groups have been replaced with hydroxy groups.
Claim 17
Dependent Claim 33 words
The silane end-capped polyarylene polyether of claim 9 wherein E represents the residue of hydroquinone, 2,2-bis(4-hydroxyphenyl)propane, 4,4'-thiodiphenol, p,p'-biphenol or bis(4-hydroxyphenyl) sulfone, and wherein E' represents the residue of 4,4'-dihalodiphenyl sulfone, 4,4'-dihalobenzophenone, or 4,4'-bis(4-halophenylsulfonyl)biphenyl.
Claim 18
Dependent Claim 24 words
The silane end-capped polyarylene polyether of claim 9 wherein E represents the residue of 2,2-bis(4-hydroxyphenyl)propane, and wherein E' represents the residue of 4,4'-dihalodiphenyl sulfone.
