摘要:
Polymer blend comprising components A, B and C: A: 1 to 19.5% by weight of an elastomeric block copolymer A based on styrene (S-TPE); B: 0.5 to 8% by weight of a compatibilizer component B; and C: 80 to 98.5% by weight of at least one semi-crystalline olefin homo- or copolymer C. The invention further relates to a composition comprising thermoplastic elastomers based on styrene (S-TPE) for use as compatibilizer of S-TPE block copolymers and polyolefins, a process for the preparation of the polymer blend, a master batch for the preparation of the polymer blend, and single- and multilayer films comprising said polymer blend and their use for food packaging and as shrink hood.
摘要:
The present invention relates to a polymer part P of a wind turbine blade (W) comprising: (I) a thermoplastic component containing a thermoplastic copolymer matrix A including optionally substituted styrene and acrylonitrile and a graft copolymer B containing a graft base comprising C 1 -C 8 -alkyl(meth)acrylate and a graft shell, (II) optionally one or more fibers that may optionally react with the copolymer matrix A, (III) optionally one or more polycarbonates, and optionally one or more further components. Further, the invention refers to methods for preparing such polymer part P in a system for protecting and/or repairing a wind turbine blade (W) and a kit for this purpose.
