Covalent Adaptable Networks with Tunable Exchange Rates Based on Reversible Thiol–yne Cross-Linking

The design of covalent adaptable networks (CANs) relies on the ability to trigger the rearrangement of bonds within a polymer network. Simple activated alkynes are now used as versatile reversible cross-linkers for thiols. The click-like thiol–yne cross-linking reaction readily enables network synthesis from polythiols through a double Michael addition with a reversible and tunable second addition step. The resulting thioacetal cross-linking moieties are robust but dynamic linkages. A series of different activated alkynes have been synthesized and systematically probed for their ability to produce dynamic thioacetal linkages, both in kinetic studies of small molecule models, as well as in stress relaxation and creep measurements on thiol–yne-based CANs. The results are further rationalized by DFT calculations, showing that the bond exchange rates can be significantly influenced by the choice of the activated alkyne cross-linker.

Sulfur-containing cycloaliphatic compound, filled sulfur-vulcanizable elastomer composition containing sulfur-containing cycloaliphatic compound and articles fabricated therefrom

A sulfur-containing cycloaliphatic compound, useful as a crosslinker for filled sulfur-vulcanizable elastomer compositions, is represented by the general formula: [in-line-formulae]G[-CaH2a—S[C(═O)]bR]n [/in-line-formulae] wherein G is selected from the group consisting of: saturated, monocyclic aliphatic group of valence n containing from 5 to 12 carbon atoms and optionally containing at least one halogen, andsaturated monocyclic silicone [RSiO—]n[R2SiO—]p group of valence n; wherein each R independently is a hydrogen or monovalent hydrocarbon of up to 20 carbon atoms; each occurrence of subscripts a and b independently is an integer wherein a is 2 to 6 and b is 0 or 1; p is an integer of from 0 to 3; and, n is an integer of from 3 to 6, with the provisos that when b is 0, R is a hydrogen atom, and when G is a non-halogenated, saturated monocyclic aliphatic group of 6 carbon atoms, n cannot be 3.

Compositions for tissue augmentation

Methods for making biomaterials for augmentation of soft and hard tissues, kits containing precursors for forming the biomaterials, and the resulting biomaterials are described herein. The biomaterials are formed from at least a first and a second precursor component. The first precursor component contains at least two nucleophilic groups, and the second precursor component contains at least two electrophilic groups. The nucleophilic and electrophilic groups of the first and second precursor components form covalent linkages with each other at physiological temperatures. The precursors are selected based on the desired properties of the biomaterial. In the preferred embodiment, the first precursor is a siloxane. Optionally, the biomaterials contain additives, such as thixotropic agents, radiopaque agents, or bioactive agents. In the preferred embodiment, the biomaterials are used to augment at least one vertebra of the spine (vertebroplasty).
