Patent ID: 8575245

Claim:
A polymer composition, comprising: a) a polymer selected from the group consisting of: wherein: each occurrence of R a is independently hydrogen or an optionally substituted group selected from the group consisting of C 1-30 aliphatic; C 1-30 heteroaliphatic having 1-4 heteroatoms independently selected from the group consisting of nitrogen, oxygen, and sulfur; 6- to 10-membered aryl; 5- to 10-membered heteroaryl having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur; and 3- to 7-membered heterocyclic having 1-3 heteroatoms independently selected from the group consisting of nitrogen, oxygen, and sulfur; and each occurrence of R b , R c , and R d is independently hydrogen or an optionally substituted group selected from the group consisting of C 1-12 aliphatic; C 1-12 heteroaliphatic having 1-4 heteroatoms independently selected from the group consisting of nitrogen, oxygen, and sulfur; 6- to 10-membered aryl; 5- to 10-membered heteroaryl having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur; and 3- to 7-membered heterocyclic having 1-3 heteroatoms independently selected from the group consisting of nitrogen, oxygen, and sulfur; wherein any of (R a and R c ), (R c and R d ), and (R a and R b ) can be taken together with their intervening atoms to form one or more optionally substituted rings; and b) an additive comprising an organic cation characterized in that its presence modulates the decomposition temperature of the polymer composition; wherein the additive is present at a concentration in the range of about 100 to 3500 ppm by weight; wherein the polymer composition comprises transition metals in an amount less than 10 ppm.
