This invention relates to a process for using computerized molecular interaction modeling to predict the adhesive interactions between a substrate and a polymer. The molecular modeling method may be used to predict and select optimal adhesion promoting monomers for use in latex polymer coatings, providing the best wet adhesion to alkyd-coated substrates. The molecular modeling method could also predict substrate polymer pairs having the least affinity, and thus the most useful as a release liner. The method involves the steps of:

Method for predicting adhesive interactions using molecular modeling

This invention relates to a method for controlling copolymer architecture by a two-part process. In the first step, a monomer analysis is obtained from a test polymerization having constant rate co-monomer addition. In the second step a copolymer is polymerized using a co-monomer feed rate that has been adjusted based on the monomer analysis to produce a copolymer with highly controlled polymer architecture. The method can predict feeds rates to produce any desired polymer architecture from a purely random polymer to a tapered polymer. The method works for terpolymers as well as copolymers.
