TPE's which comprise A blocks or B blocks or both A blocks and B blocks, which are crystalline and in which at least a part of the crystallinity result from the presence of crystallizable side chains. Such crystalline blocks are referred to as SCC blocks. TPE's containing SCC A blocks are novel and as such form part of the present invention. The invention also includes processes, compositions, shaped articles and assemblies which make use of TPE's containing SCC A blocks.

Thermoplastic elastomers

Thermoplastic elastomers (TPEs) containing side chain crystalline (SCC) blocks. The SCC blocks my be hard (A) blocks or the soft (B) blocks (or both) in the TPE. Some of these TPEs are novel, e.g. those in which A blocks are SCC blocks, and the B blocks are polyethers, polyacrylates, polyamides, polyurethanes or polysiloxanes. The SCC-containing TPEs are particularly useful as matrix materials for other components which are dispersed therein, e.g. energetic solids and other thermally responsive materials.
