Abstract
Dense star polymers or dendrimers, modified by capping with a hydrophobic group capable of providing a hydrophobic outer shell, act as molecular nucleating agents in forming a polymer blend.
Claims17
A polymer blend comprising a foamable modified dense star polymer or dendrimer, which has a highly branched interior of one monomeric composition and an exterior structure of a different monomeric composition capable of providing a hydrophobic outer shell and which have a particle diameter of from about 5 to about 1,000 nanometers (nm), and a matrix polymer.
