Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
85 words
A method of forming an adhesive bond between two substrates which comprises subjecting a composite comprising said two substrates and a layer between said substrates of the 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, to at least contact pressure and to a temperature of at least the glass transition temperature of said polyarylene polyether.
Claim 2
Independent Claim
85 words
A method of forming an adhesive bond between two substrates which comprises subjecting a composite comprising said two substrates and a layer between said substrates of the 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, to at least contact pressure and to a temperature of at least the glass transition temperature of said polyarylene polyether.
Claim 3
Dependent Claim
47 words
An article comprising a substrate and adhering thereto 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 4
Dependent Claim
47 words
An article comprising a substrate and adhering thereto 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 5
Dependent Claim
12 words
The article of claim 2 wherein said substrate is a fibrous material.
Claim 6
Dependent Claim
25 words
The article of claim 3 wherein said fibrous material is glass fibers and said silane end-capped polyarylene polyether is a sizing for said glass fibers.
Claim 7
Dependent Claim
18 words
A composite comprising thermoplastic polyarylene polyether containing, as a reinforcing filler, the sized glass fibers of claim 4.
Claim 8
Dependent Claim
47 words
A blend of a thermoplastic polyarylene polyether and 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 9
Dependent Claim
47 words
A blend of a thermoplastic polyarylene polyether and 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 10
Dependent Claim
26 words
The blend of claim 6 wherein the said thermoplastic polyarylene polyether is the thermoplastic reaction product of an alkali metal salt of 2,2-bis(4-hydroxyphenyl)propane and 4,4'-dihalodiphenyl sulfone.
Claim 11
Dependent Claim
44 words
A method of forming the article of claim 2 which comprises subjecting a substrate having at least a portion of its surface coated with said silane end-capped polyarylene polyether to an elevated temperature for a period of time sufficient to cure said polyarylene polyether.
Claim 12
Independent Claim
84 words
A method of preparing a shaped polyarylene polyether article which comprises providing a composition comprising 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, melt fabricating said composition to form a shaped article, and then subjecting said shaped article to an elevated temperature for a period of time sufficient to cure said polyarylene polyether.
Claim 13
Independent Claim
84 words
A method of preparing a shaped polyarylene polyether article which comprises providing a composition comprising 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, melt fabricating said composition to form a shaped article, and then subjecting said shaped article to an elevated temperature for a period of time sufficient to cure said polyarylene polyether.
Claim 14
Dependent Claim
69 words
The method of claim 9 wherein the silane end-capped polyarylene polyether composition has at least some of the hydrolyzable substituent groups hydrolyzed by a method which comprises contacting said polyarylene polyether in finely divided solid form with water at a temperature below the glass transition temperature of said polyarylene polyether for a period of time sufficient to hydrolyze at least some of said hydrolyzable groups to silanol hydroxyl groups.
