Abstract
The invention relates to polymer foam particles, both in expanded and partly expanded form, from a polymer matrix based on a blend comprising polybutylene terephthalate and polyethylene terephthalate, to a process for production thereof, and to the use of polyethylene terephthalate for broadening the processing window of polybutylene terephthalate-based polymer foam particles in processing to give mouldings.
