Influence of Chemical Modification with Polycrease ECR on the Functional Performance of Poplar wood Polymer

In this research the effect of chemical modification with Polycrease ECR on the functional performance of poplar wood to use as wood polymer were investigated. Polycrease ECR the modified dimethyloldihydroxy-ethyleneurea (DMDHEU) was used for chemical modification of wood by impregnation method. Spe...
