Abstract
The present invention relates to a stretchable blend comprising a stretchable liquid crystal polymer and a thermoplastic. These stretchable blends can be stretched at the same temperature range as many conventional thermoplastics. During a post orientation process, such as fiber or film stretching, the stretchable liquid crystal polymer can stretch and deform along with the thermoplastic matrix maintaining adhesion between the liquid crystal polymer domains and the thermoplastic matrix thereby improving the physical properties of the oriented article.
