Abstract. We report a new strategy for the crosslinking of low density polyethylene (LDPE) by using a small amount of functional nanostructured hybrid agent, octavinyl polyhedral oligomeric silsesquioxane (OVPOSS), as the crosslinker, which dramatically decreases the amount of dicumyl peroxide (DCP) and thus avoids the chain scission, scorch, and ...

High-,Density, Crosslinked ,Polyethylene, (XLPE) High-,density, crosslinked ,polyethylene,, or XLPE, is a thermoset resin that is specifically designed for critical applications like chemical storage. During the XLPE manufacturing process, a catalyst (peroxide) is built into the resin, which creates a free radical.

In particular, the influence of the network ,crosslinking density,, swelling ratio, and chemical composition on the ability of encapsulated chondrocytes to form extracellular matrix is examined. The cartilage produced in these hydrogels will be quantified using biochemical assays that measure DNA content and the amount of sulfated glycosaminoglycans and total collagen in the extracellular matrix.

An explanation for the increased water uptake ability with increased UV irradiation could be that drying the gels causes partial reversible collapse of pores in the gel meshwork as has been observed for similar gels by Wu et al. [17], with an increased degree of pore collapse for shorter ,crosslinking, times. Increasing the ,crosslinking, time would increase the ,crosslinking density, and thereby ...
