The effect of cross-linking chain length on mechanical properties of a dough-molded poly(methylmethacrylate) resin. 1992

S Caycik, and R G Jagger

University of Wales College of Medicine, Dental School, Cardiff.

Three different cross-linking agents which provide a range of cross-linking chain lengths and flexibilities were added to the monomer component of a dough-molded poly(methylmethacrylate) resin in various concentrations, and their effects on the impact strength, transverse bend strength, and tensile strength of the cured polymer were investigated. Increase in the chain lengths of cross-linking agents led to a decrease in the properties of transverse bend strength and tensile strength and an increase in the property of impact strength.

D003432	Cross-Linking Reagents	Reagents with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between side chains of amino acids in proteins; the locations of naturally reactive areas within proteins can thereby be identified; may also be used for other macromolecules, like glycoproteins, nucleic acids, or other.
