<p>Resin moldings having elasticity and stretchability equivalent to those of rubber of the prior art, and a process for the production of the moldings. The resin moldings are made mainly of a polyolefin produced by polymerization with a metallocene catalyst, have permanent set, and are stretchable. The moldings can be produced by a process comprising the step of stretching a molding mainly made of a polyolefin produced by polymerization with a metallocene catalyst to thereby give permanent set to the molding.</p> |
