WebHowever, to link the effect of these phenolics, the complete quantification of the whole fruit is mandatory. The objective of this research was therefore to conduct proximate analysis and to determine the Total Phenolic Content (TPC) in different constituents of A. garckeana fruit for use as a natural crosslinking agent in gelatin resin. WebEventually chemicals other than sulfur were used to crosslink elastomers, resulting in the term crosslinking to become synonymous with vulcanization. Vulcanization is normally achieved with time and temperature activation of specific chemicals which react with polymeric materials, producing a crosslinked network of molecular chains with visco ... build locally
