Succinic acid can be used as a cross-linking agent having two free carboxylic groups (Fig. Ashland has received US patent 9,539,795 for its PureKote 23589 dispersion and PureKote 21412A cross-linking agent coating system.
Crosslinking AgentsX. Crosslinking is the formation of chemical links between molecular chains to form a three-dimensional network of connected molecules. The vulcanization of rubber using elemental sulfur is an example of crosslinking, converting raw rubber from a weak plastic to a highly resilient elastomer.
The cross-link density of model acrylated triglycerides was investigated by LaScala and Wool and was found to increase with the acrylation level for samples with and without styrene (Figure 7.5).The cross-link density was higher for samples without styrene because styrene is a linear chain extender and therefore does not contribute to cross-linking.
These covalent adducts are formed by linking the 3, 4 or 4', 5' edge of psoralen to the 5, 6 double bond of thymine. Psoralens can form two types of monoadducts and one diadduct (an interstrand crosslink) with thymine. These adducts result in local distortions to DNA at the site of intercalation.
In chemistry and biology a cross-link is a bond that links one polymer chain to another. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic polymers or natural polymers (such as proteins ).
Decellularised and Chemically Cross linked Human Umbilical Vein as a Small Caliber Conduit--Scaffold for Vascular Tissue Engineering (1) The solution of polymer P, crosslinking agent A, and coagulant B were mixed in accordance with the ratio of the experimental schemes and stirred evenly.

Cross-linking. Corneal collagen cross-linking is a developing treatment which aims to strengthen the cornea, however, according to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. In 2016, however, the FDA approved cross-link surgery as a treatment for keratoconus. Radial keratotomy
An effective cross linking agent for Type I collagen to replace sutures or attach tissue to other materials is a research objective of this and other research groups (1–8). However, application of these techniques to tissue cross linking has been particularly challenging because of difficulties arising from biological incompatibility as well as the restrictions on physical and chemical properties which …
