Title: Ian D Robertson: Innovator in Polymer Chemistry
Introduction
Ian D Robertson is a notable inventor based in Collegeville, PA (US). He has made significant contributions to the field of polymer chemistry, holding 4 patents that showcase his innovative approach to creating advanced materials.
Latest Patents
Robertson's latest patents include a composition for an aqueous dispersion of occluded polymer particles. This invention relates to a formulation that comprises multiphase polymer particles, which are designed to create a water-resistant blister-free LASD coating with minimal surface defects. The first polymer particles have a Tof of less than 30° C., while the second polymer particles have a Tin ranging from 100° C. to 110° C. The second polymer particles are phase-separated and occluded within the first polymer particles, with a number average molecular weight between 9,000 to 25,000 g/mole.
Another significant patent by Robertson details the process for preparing an aqueous dispersion of multiphase occluded polymer particles. This process involves emulsion polymerization conditions, where first monomers and a chain transfer agent are used to form an aqueous dispersion of first polymer particles. The second monomer, which comprises at least 90 weight percent methyl methacrylate, is then added to create the occluded polymer particles. This innovative process also aims to produce a water-resistant blister-free LASD coating.
