Polymer Entity Tagger

The polymer entity tagger (PET) finds and tags polymer names in text. It currently tags IUPAC, acronym and traditional names. Please see the examples.

PET is based on the distilRoBERTa base model from Hugging Face and fine-tuned on a large dataset with annotated polymer names.


  • The poly(alkyl acrylates) were prepared by reacting poly(acrylic acid) with different alkyl alcohols (octyl, dodecyl, tetradecyl alcohols).
  • The dispersion was filtered through polyester gauze to remove the excess water.
  • A widely used engineering aromatic polymer is poly(phenylene sulfide) (PPS), a semicrystalline thermoplastic constituted of alternating para-substituted phenylene rings and divalent sulfide moieties.
  • It is well established that PHB is miscible with poly(vinyl chloride) (PVC), poly(vinylidine fluoride) (PVDF), poly(4-vinylphenol) (PVPh), poly(ethylene oxide) (PEO), poly(epichlorohydrin) (PECH), some cellulose esters, and poly(vinyl acetate) (PVAc) .
  • Miscibility in blends involving copolymers of styrene and acrylonitrile (SAN's) has been an interesting subject of diversified studies. Most notably, the miscibility of SAN with poly(methyl methacrylate) (PMMA) and with poly(ε-caprolactone) (PCL) has been widely reported since 1974. Miscibility in SAN with acrylic polymers other than PMMA has not been reported until lately (1991) when Kishore et al. and Mandal et al. independently and simultaneously reported miscibility of poly(phenyl acrylate) with SAN's (15-35 or 11.5-32 wt % AN, respectively). In many reported miscible binary blend systems whose constituents involve at least one copolymer, it has been commonly observed that miscibility occurs in a range of copolymer compositions. This phenomenon has been attributed to the so-called "copolymer effect" by some investigators. The "copolymer effect" suggests that mutual repulsion between the constituents (copolymer units) of the copolymer prevails over other interactions and that the repulsion in the copolymer leads to miscibility in the homopolymer-copolymer pair.
