Abstract:
Methods may include modifying the crystallization properties of a polymer composition including a polyolefin and a nucleating agent with the structure:
wherein R1 and R2 are independently hydrogen, alkyl, alkenyl, or aryl with the proviso that at least one of R1 or R2 is a carbon chain having 1 to 12 carbons with at least one of the carbons in the carbon chain covalently bound to the polyolefin, and wherein the alkyl, alkenyl, or aryl may be substituted with one or more carboxylate groups; and M is a metal selected from Group I of the Periodic Table.
wherein R1 and R2 are independently hydrogen, alkyl, alkenyl, or aryl with the proviso that at least one of R1 or R2 is a carbon chain having 1 to 12 carbons with at least one of the carbons in the carbon chain covalently bound to the polyolefin, and wherein the alkyl, alkenyl, or aryl may be substituted with one or more carboxylate groups; and M is a metal selected from Group I of the Periodic Table.
