Research data for "Thermoplastic-like heterogeneous photopolymers for additive manufacturing with tailored hyperbranched rubbers"

Context

This dataset was created from original work conducted in the framework of a PhD project at University of Chemistry and Technology Prague and an Erasmus-Exchange to TU Wien, and compiled in a publication. It provides the raw data of results presented and discussed therein. The data is published within below-referenced publication.
