Abstract: Using a novel water-soluble, active ester amide-containing functionalized controlled radical polymerization initiator, stimuli responsive polymers have been grown from the surface of a protein, exemplified by chymotrypsin or any protein having surface amino acids that will covalently bind to the active ester amide-containing functionalized initiator. It is shown that changes in temperature or pH can change the conformation of the polymer surrounding the enzyme, which in turn enabled the rational tailoring of enzyme activity and stability. This method has afforded an increase in the activity and stability of the enzyme by an order of magnitude at pH's where the enzyme is usually inactive or unstable. Multimodal temperature responsive protein-block copolymer conjugates are described.

Abstract: The present invention is generally directed to a new class of TPEs made from peptide terminated low Tg polymers and methods for making them. The middle block of these TPE is a telechelic polymer with a Tg that is below the intended service temperature of the TPE. The terminal peptide segments of these TPEs are short (from about 1 to about 10 amino acids long) and tend to from sheet type secondary structures through intermolecular hydrogen bonds, creating physical crosslinks between polymer chains. The dissimilarity of the peptide hard component and the elastomeric soft component results in very strong segregation between the microphase domains and a low plastic deformation for the resulting TPE. And since the Tm of the crystalline peptide phase can be adjusted, these new TPEs may be tailored to fit the intended service temperature and are melt-processable.

Most importantly, this class of bio-based block polymers shows promise as providing sustainable yet scalable and tunable thermoplastic elastomers and pressure-sensitive adhesives, among other applications.

Abstract: Epoxidized fatty acid alkyl esters and methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing fatty acid alkyl esters with an acid and a peroxide. Epoxidation can be performed under controlled reaction conditions to provide epoxidized fatty acid alkyl esters having an iodine value in the range of from 4 to 15 g I2/100 g of epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizer compositions, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.
