چکیده

VistamaxxTM Specialty Elastomers are polyolefin elastomers with isotactic propylene crystallinity. These polymers contain a predominant (>80%) amount of propylene with isotactic propylene crystallinity, with the balance of the composition being ethylene and other αolefins. This new family of thermoplastic elastomers are highly elastic and exhibit excellent recovery from deformation. These polymers share the processability of conventional polyolefins such as polyethylene and isotactic polypropylene and can, thus, be easily formed into spunbond and meltblown nonwoven fabrics using conventional plastic processing processes. The paper will discuss the processing and elastic properties of nonwoven fabrics made using these polymers, with an emphasis on the influence of polymer characteristics and processing conditions on the elastic behavior of the fabrics.

Positron Annihilation Lifetime in situ Study of Deformed Polyolefin Elastomers

The positron annihilation lifetime spectroscopy was used to investigate the free volume hole size of ethylene octane copolymers as a function of deformation in the range from 0 to 110% in steps of 10%. For each degree of deformation a series of 5–6 positron annihilation lifetime spectra was collected in situ. All spectra of a given series were analysed simultaneously. They were resolved into th...
