Suppressing Creep and Promoting Fast Reprocessing of Vitrimers with Reversibly Trapped Amines

We report a straightforward chemical strategy to tackle current challenges of irreversible deformation in low Tg vitrimers at operating temperature. In particular, vinylogous urethane (VU) vitrimers were prepared where reactive free amines, necessary for material flow, were temporarily shielded inside the network backbone, by adding a small amount of dibasic ester to the curing mixture. The amines could be released as reactive chain ends from the resulting dicarboxamide bonds via thermally reversible cyclisation to an imide moiety. Indeed, (re)generation of the required nucleophilic amines as network defects ensured reprocessing and rapid material flow at higher temperature, where exchange dynamics are (re)activated. As a result, VU vitrimers were obtained with limited creep at service temperature, yet with good reprocessability at elevated temperatures. Thus, by exerting strong control on the molecular level over the availability of exchangeable functional groups, a remarkable improvement of VU properties was obtained.

METHOD FOR PREPARATION OF ACETOACETATE ESTER COMPOUNDS

The invention discloses a method for preparation of acetoacetate ester compounds with amino alcohol catalysts which are themselves diketenized in the course of the diketenization reaction; and subsequent polymerization of these acetoacetate ester compounds with e.g. acrylate compounds to provide resins, whereby the acetoacetylated amino alcohol catalyst partakes in the polymerization reaction.

Transacetoacetylation with tert-Butyl Acetoacetate: Synthetic Apllications

Reaction of various nucleophiles with tert-butyl acetoacetate (t-BAA, 1a) is shown to be a convenient method for the preparation of a wide variety of acetoacetic acid derivatives.This material can be used to prepare acetoacetates and acetoacetamides from a wide variety of alcohols and amines.Reaction of 1a with an unhindered primary amine such as n-heptylamine under standard conditions gives unwanted byproducts due to the formation of the enamines 24 and 25.Formation of these byproducts can be minimized by dilution and/or altering the mode of addition.
