Abstract
Official abstract text for this publication.
Disclosed are ester compounds of the formulae wherein R c is alkylene, arylene, arylalkylene, or alkylarylene as further defined herein, R d is alkylene, arylene, arylalkylene, or alkylarylene as further defined herein, and m and n are integers representing the numbers of repeat monomer units. The materials are suitable for use in inks and other applications.
First claim
Opening claim text (preview).
What is claimed is: 1. A compound of the formula wherein R c is: (i) alkylene, including substituted and unsubstituted alkylene, wherein hetero atoms either may or may not be present in alkylene; (ii) arylene, including substituted and unsubstituted arylene, wherein hetero atoms either may or may not be present in arylene; (iii) arylalkylene, including substituted and unsubstituted arylalkylene, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of arylalkylene; or (iv) alkylarylene, including substituted and unsubstituted alkylarylene, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of alkylarylene; and n is an integer representing the number of repeat monomer units and is at least 2. 2. A compound according to claim 1 wherein R is —(CH 2 ) 4 —. 3. A compound according to claim 1 wherein R c is 4. A compound according to claim 1 having a % BRC of at least about 80%. 5. A compound according to claim 1 wherein n is from about 2 to about 10. 6. A compound according to claim 1 wherein n is no more than about 10. 7. A compound according to claim 1 having a weight average molecular weight of from about 600 to about 10,000 g/mol. 8. A compound according to claim 1 having a % BRC of at least about 60%. 9. A compound according to claim 1 having a polydispersity of from about 1 to about 2. 10. A compound according to claim 1 having a Tg of from about 1° C. to about 30° C. 11. A compound of the formula wherein R c is: (i) alkylene having from about 2 to about 40 carbons, including substituted and unsubstituted alkylene, wherein hetero atoms either may or may not be present in alkylene; (ii) arylene having from about 6 to about 40 carbons, including substituted and unsubstituted arylene, wherein hetero atoms either may or may not be present in arylene; (iii) arylalkylene having from about 7 to about 40 carbons, including substituted and unsubstituted arylalkylene, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of arylalkylene; or (iv) alkylarylene having from about 7 to about 40 carbons, including substituted and unsubstituted alkylarylene, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of alkylarylene; and n is an integer representing the number of repeat monomer units and is from about 2 to about 10. 12. A compound according to claim 11 having a weight average molecular weight of from about 600 to about 10,000 g/mol and a Tg of from about 1° C. to about 30° C. 13. A compound of the formula wherein R c is: (i) alkylene having from about 4 to about 12 carbons, including substituted and unsubstituted alkylene, wherein hetero atoms either may or may not be present in alkylene; (ii) arylene having from about 6 to about 16 carbons, including substituted and unsubstituted arylene, wherein hetero atoms either may or may not be present in arylene; (iii) arylalkylene having from about 7 to about 16 carbons, including substituted and unsubstituted arylalkylene, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of arylalkylene; or (iv) alkylarylene having from about 7 to about 16 carbons, including substituted and unsubstituted alkylarylene, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of alkylarylene; and n is an integer representing the number of repeat monomer units and is from about 2 to about 10.
