For making damping materials with broader zone of temperature and frequency, extending the damping functional zone of chlorinate butyl rubber to higher temperature, interpenetrating polymer network(IPN)is produced based on chlorinate butyl rubber mixed with poly(methyl)acrylate (PMAC).

STUDIES ON DAMPING MATERIALS OF POLYPHENYLSILOXANE/POLYACRYLATE SIN;

Studies on the mechanical property of PDAAM/PU interpenetrating polymer networks;

A new method was advocated to design distribution of gradient component in gradient interpenetrating polymer networks(IPNs), gradient IPNs of different number of layers were prepared by means of casting layer by layer, and their tensile properties were studied.

Poly(propylene carbonate) polyurethane/poly(methylmethacraylate) interpenetrating polymer networks(PPCPU/PMMA IPNs) was synthesized by simultaneous methods.

This paper reviewed the worldwide advances of polymer damping materials featured of interpenetrating network developed in the past few years.

Some new studies on the toughening methods of epoxy resin,such as interpenetrating polymer network,thermoset liquid crystal polymer,core-shell polymer and nano-particles,and their recent progress were introduced in detail in this paper.

A series of rigid interpenetrating polymer network(IPN) foams,based on polyurethane(PU) and epoxy resin(EP),were prepared by a simultaneous polymerization technique.

Four kinds of grafted interpenetrating polymer networks(IPNs) were obtained from castor oil,toluene diisocyanate(TDI),monohydroxy-terminated acrylic (or methacrylic ) prepolymer and /or acrylic(methacrylic) monomer in the presence of dibutyltin dilaurate and redox initiators.
