Blends and IPNs of Natural Rubber with Acrylic Plastics

Acrylate polymers are synthetic compounds produced by bonding acrylic acid or acrylic ester with other molecules. They can be used as dispersants, thickeners, adhesives and binders. They can provide the desirable characteristics by blending or forming into interpenetrating polymer networks (IPNs) with natural rubber that are popular materials and widely accepted to create the new substances in material engineering. These blends and IPNs are one type of thermoplastic natural rubbers which combine the typical advantages of physical properties in both acrylic thermoplastics and rubber. Thermoplastic natural rubbers can be processed in a molten state and repeated following by a thermoplastic property, and they exhibit the typical properties of rubber. When they are heated at high temperature in extrusion, injection and compression moulding stage, they show the individual chains slip to plastic flow. When they are cooled, the molecular chains are once again held firmly of rubber. When subsequently heated, the chains slip again to plastic flow. Furthermore, the natural rubber can be improved the impact strength and flexibility of the thermoplastic materials to the new blended substances that are generally lower modulus and higher elasticity than pure acrylic plastics. The various techniques, i.e. morphological, mechanical, thermal, rheological, dielectric and scattering studies are used to describe the properties of natural rubber blends and IPNs with different types of acrylic polymers. Many advantaged properties of them are widely developed in industrial applications such as automotive, household appliances, medical devices, electrical cables, and headphone cables.
