Abstract Oligomer systems based on poly(lactic acid) (PLA), poly(glycolic acid) (PGA), poly(butylene succinate)
(PBS) and poly(butylene adipate) (PBA) were impregnated in wood and polymerized in situ to improve
the dimensional stability of the treated wood. Dynamic mechanical thermal analysis (DMTA) was used
to characterize the impact on the treated wood properties. Cell wall bulking treatments (PLA and PGA
oligomers: OLA and OGA) induced softening and plasticization of wood components. Lumen fi lling
treatments (PBS and PBA oligomers: OBS and OBA) led to minor decreases in treated wood stiffness with any
softening dependent on the polymer melt temperature. Overall, no oligomer treatment… More >
