24 - The ( silicone / polypropylene ) elastomers are very flexible at low temperatures and yet are stable at temperatures as high as 250 degrees C.2Q25 - A ( styrene / latex ) is a stable suspension of small insoluble polymer particles dispersed in water. 2Q26 - ( Addition / Condensation ) polymerization is a process by which monomer units are attached one at a time in chainlike fashion to form a linear macromolecule.2Q27 - The flexibility, ductility and toughness of polymers may be improved with the aid of additives called ( promoters / plasticizers ).2Q28 - The ( extrusion / compression ) process is the molding of a heated viscous thermoplastic under pressure through an open-ended die.2Q29 - The two main constituents in a Composite are the ( filler / reinforcement ) and the( matrix / catalyst ).4Q30 - The process where either wetted or prepreg fibers are wound on a mandrel is called( composite molding / filament winding ). 4
