Abstract
A highly elastic and easily stretchable permanently shaped reticular web of an elastomeric and thermoplastic film forming composition which comprises a thermoplastic elastomeric component consisting essentially of linear or radial A-B-A block copolymers or mixtures of these linear or radial A-B-A block copolymers with simple A-B block copolymers. A resin component also may be included.
Claims8
A permanently heat shaped elastic and thermoplastic reticular web which comprises strands intersecting in a pattern and defining a corresponding pattern of holes, said web being formed from an elastomeric and thermoplastic composition which comprises an elastomeric component and about 0-200 parts of a resin component per one hundred parts by weight of the elastomeric component, said elastomeric component consisting essentially of linear or radial A-B-A block copolymers or mixtures of these linear or radial A-B-A copolymers with simple A-B block copolymers, said A-blocks being derived from vinyl arenes and said B-blocks being derived from conjugated dienes or lower alkenes, and said web being easily stretchable and elastic and adapted to recover from deformation without substantial loss of its permanent shape.
