Abstract
An additive manufacturing composition for powder bed processes is described. The composition includes at least a first type of impact modified polymer beads. The polymer beads include a) an acrylic or vinyl (co)polymer matrix, and b) an impact modifier in which at least 85% w/w of the first type of impact modified polymer beads have a particle size of between ≥20 μm and ≤200 μm and/or on average the impact modified polymer beads have greater than 5% w/w impact modifier. Also disclosed is an additive manufacturing process for a production of a three dimensional product comprising fused impact modified polymer particles. The use of a composition in additive manufacturing, an additive manufacturing cartridge or replacement hopper and a process for the production of impact modified polymer beads by a suspension polymerization process is also disclosed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
