The polymerization occurs through a nucleophilic substitution reaction of DCDPS as difunctional nucleophiles with bisphenol A in dimethyl sulfoxide, DCDPS forms a material called Udel.
Suitable polyols for use in the present invention include difunctional and trifunctional alcohols, and the acids include aliphatic and aromatic polycarboxylic acids and their esters.
These are multifunctional or linear difunctional silicone prepolymers with reactive terminal end groups that allow modification of coating performance through incorporation of silicone moieties into coating resins and binders.
Terminologies such as tailored bimodal or controlled long-chain branching discuss the addition of difunctional diene monomers such as vinylnorbomene or hexadiene comonomers that essentially couple the polymer chains to form an H-branched structure.
The biorefineries produce Inherent renewable building blocks, including renewable C10+ olefins and high-value, difunctional specialty chemicals with superior functional attributes, that were previously unavailable commercially until now.
