A graft copolymer of a vascular plant having a biologically produced part that is the plant or a component thereof and at least one sidechain, Sc, having randomly repeat unit, Rru, wherein Rru are formed by the polymerization of at least one substituted ethene polymerable by free radical polymerization. The sidechain repeat unit, Rru, has the structure <IMAGE> such that the side groups, Ri where i=1 to 4, on the sidechain are selected from the group of alkanes, alkenes, amides, alcohols, alkoxides, aromatics, cycloalkanes, esters, halogens, hydrogen, phenols, and nitrile groups and such groups further substituted with one or more groups. The side groups on the sidechain may vary from one repeat unit to another. The number of sidechains on the woody plant fragment can vary from 1 to 500 and the number of repeat units in each sidechain can vary from 1 to 500,000. The invention provides a vascular plant or component thereof, chemically bound to a polymerized chain of repeat units from ethene monomers which possess the desirable properties of a thermoplastic, the desirable properties of a macromolecular surfactant, the desirable properties of a thermoplastic which degrades completely in the environment, the desirable properties of a controlled release agent, and the desirable features of a wood-reinforced, thermoplastic composite.
