The setting up of chemical links between molecule chains. This occurs in all thermosetting resins. Styrene monomer is a crosslinking agent in polyester resins.
Property of a solid support prepared from polymeric materials with interconnected strands. Often results from the inclusion of multifunctional monomers in the polymerization reaction, e.g. divinylbenzene in polystyrene production. In such cases, the degree of crosslinking is often quoted as the proportion of the multifunctional monomer in the reaction mixture. The extent of crosslinking is important for physical properties of the solid support, such as the propensity to swell in different solvents.
Formation of chemical bonds between polymer chains leading to the formation of a three dimensional network. Final materials are called thermosets.
The formation of side bonds between different polymer strands which leads to a change in the physical properties of the material, such as loss of flexibility and colour change.
The formulation of bonds between molecular chains in a polymer by means of chemical canalization or electron bombardment. The properties of the resulting thermosetting material are usually improved.
When rubber is heated to the required temperature, peroxide decomposes to form free radicals that react with the organic groups in the silicone polymer. In an addition cured silicone rubber, the catalyst activates the reaction between the crosslinker and reactive organic groups in the silicone polymer. This results in crosslinking between organic groups. The number and position of these linkages determine the degree of vulcanization.
crosslinking is when individual polymer chains are linked together by covalent bonds to form one giant molecule. (see: elastomer, thermoset)
Process of bridging individual rubber molecules through the formation of covalent chemical bonds between the rubber molecules.
Molecular bonding that is the basis of most polymerisation curing processes in adhesives, silicones, inks, varnishes and plates.
Formation of chemical bonds between polymer chains leading to the formation of a three dimensional network. This kind of process has the effect of producing gel in a thermoplastic polymer or converting it into a thermoset polymer.
Process by which a substance will react chemically with the molecular chains of a thermoplastic material, and by linking them together create a more rigid structure resulting in a more or less infusible product.
The setting up of chemical links between molecular chains to form a three dimensional network of connected molecules. The chemistry of two component resin systems.
The formation of chemical bonds between polymeric chains to yield an insoluble, three dimensional polymeric structure. Crosslinking of rubber is referred to as vulcanization or "curing".
the setting-up of chemical valence links between the molecular chains of polymer molecules, leading to the formation of a three-dimensional network of polymer chains which is infusible and insoluble. This usually reduces the thermoplasticity of the material.
The setting up of chemical links between the molecular chains of a resin to form a three-dimensional network polymer system. Crosslinking generally toughens and stiffens coatings.
Polymerization reaction that branches out from the main molecular chain to form a networked pattern of chemical links. This kind of process has the effect of producing gel in a thermoplastic polymer or converting it into a thermoset polymer.
