Abstract

The present invention provides polymers resulting from modification of polymeric moieties containing an anhydride with modifying reactant moieties. The invention further provides a wide variety of compositions comprising the and modified polymeric moieties containing an anhydride. The letters b, d, e, and z are described herein.

Claims (4)

1. A polymer resulting from modification of a polymeric moiety containing an anhydride reactant with a modifying reactant moiety wherein the modified polymer is selected from the group of structures consisting of:

wherein b, d and e are integers ranging from 0 to 10,000 with the proviso that d is non-zero, p is 10, q is 31, and z is 2-3 and the polymer is alternating, blocked or random.

2. A composition, comprising a polymer resulting from modification of a polymeric moiety containing an anhydride reactant with a modifying reactant moiety, wherein the modified polymer is selected from the group of structures consisting of:

wherein b, d and e are integers ranging from 0 to 10,000 with the proviso that d is non-zero, p is 10, q is 31, and z is 2-3 and the polymer is alternating, blocked or random.
