Cross-linking polymerization of multifunctional aromatic monomers initiated by exposure to high energy radiation continues be explored as a promising alternative thermal curing for the production high-performance composite materials. High-energy processing offers several advantages over thermosetting technology allowing fast and out-of-autoclave operations its adaptability in manufacturing larg...

This report deals with the chemically and the radiation-initiated emulsion polymerization of vinyl acetate. In experiments with potassium persulphate as initiator and sodium lauryl sulphate (SLS) as emulsifier the rate of polymerization is approximately proportional to the square root of initiator concentration and to the 0.25 power of the number of particles. The number of particles is proport...

Recently, the aerospace industry has been facing many challenges, including an increase in production rates to meet market needs. In context of adhesives and liquid shim applications, this means possibility on-demand curing. other words, must cure slowly at room temperature process be accelerated any time allow for fastest polymerization possible. However, while curing is possible several ways ...

Post-irradiation grafting of sodium styrene sulfonate (SSS) in the presence of acrylic acid (AA) has been investigated on polyethylene (PE) pre-exposed to gamma radiation at room temperature in the air. Special attention was paid to the effect of low molecular weight salt additives on the kinetics of graft copolymerization of SSS and AA. The presence of SSS links in the grafted PE copolymers wa...
