Claim Text:
1. A polymer blend comprising a bulk polymer or copolymer P B together with an amount of a polymer-dendron additive D-P D of the formula (I): wherein the polymer blend comprises from 0.001 to 50% of the dendron-additive D-P D calculated as weight of dendron D in polymers D-P D and P B ; wherein P D is the same polymer type as P B ; and P D is a polymer chain comprising at least one monomer repeat unit and is cyclic or has at least two ends and is linked to a group Y; Y is a linking group; a and b are each zero or an integer in the range from 1 to 5 wherein one b in a given generation is 0 and a in the next increasing generation is an integer from 1 to 5 and wherein a is 0 in Generation 1, 2, 3, or 4 and b is an integer from 1 to 5 in Generation 0, 1, 2, or 3; A is phenyls; each AZ is Ar(CR′) each XZ Z is O or S; and G indicates the Generation of a given dendron.
