Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
A curable polyether compound of theoretical molecular weight less than 60,000 of the formula XA m wherein: X is the residue left by the removal of m active hydrogen atoms from an initiator compound XH m ; and a is a moiety of the formula ##STR11## where: R is independently each occurrence selected from ##STR12## --CH 2 --CH═CH 2 and hydrogen; R' is independently each occurrence selected from hydrogen, halogen C 1-4 alkyl or haloalkyl and phenyl; R" is independently each occurrence a chain-terminating moiety selected from R, tertiary butyl, hydrogen, and a saturated or unsaturated ester functionality, or a chain-propagating moiety of the formula ##STR13## and y and n are numbers from zero to 500 provided that in at least one occurrence of A n is at least one, and further provided that in at least one occurrence of A, R or R" is ##STR14## or --CH 2 --CH═CH 2 .
Claim 2
Dependent Claim
152 words
A curable polyether compound of theoretical molecular weight less than 60,000 of the formula XA m wherein: X is the residue left by the removal of m active hydrogen atoms from an initiator compound XH m ; and a is a moiety of the formula ##STR11## where: R is independently each occurrence selected from ##STR12## --CH 2 --CH═CH 2 and hydrogen; R' is independently each occurrence selected from hydrogen, halogen C 1-4 alkyl or haloalkyl and phenyl; R" is independently each occurrence a chain-terminating moiety selected from R, tertiary butyl, hydrogen, and a saturated or unsaturated ester functionality, or a chain-propagating moiety of the formula ##STR13## and y and n are numbers from zero to 500 provided that in at least one occurrence of A n is at least one, and further provided that in at least one occurrence of A, R or R" is ##STR14## or --CH 2 --CH═CH 2 .
Claim 3
Dependent Claim
24 words
The curable polyether compound of claim 1 wherein R" is, in at least one occurrence of A, ##STR15## or --CH 2 --CH═CH 2 .
Claim 4
Dependent Claim
18 words
The curable polyether compound of claim 1 wherein R" is, in at least one occurrence of A, ##STR16##
Claim 5
Dependent Claim
22 words
The curable polyether compound of claim 1 wherein at least one occurrence of A R" is a saturated or unsaturated ester functionality.
Claim 6
Dependent Claim
36 words
The curable polyether compound of claim 1 wherein X is residue left by removal of m active hydrogen atoms from an initiator compound, XH m , selected from alkanols, alkenols, alkylene glycols, aliphatic polyols and phenols.
Claim 7
Dependent Claim
33 words
A cured polyether formed by exposure of a compound of claim 1 to actinic or electron beam radiation for a sufficient time to cause substantially complete reaction of the ethylenic unsaturation contained therein.
Claim 8
Dependent Claim
27 words
A curable mixture comprising Component (a) a compound of claim 1, and Component (b) an unsaturated reactive compound capable of curing with the compound of claim 1.
Claim 9
Dependent Claim
14 words
The curable mixture of claim 7 wherein Component (b) is a vinyl ester resin.
Claim 10
Dependent Claim
21 words
The curable mixture of claim 8 wherein said vinyl ester resin is the diacrylate of the diglycidyl ether of bisphenol A.
