The intern will apply the phosphorus polymer previously developed at UBC, as well as the H2O-soluble phosphorus polymers which will be prepared during the first two months of this internship, to the surface of paper and wood samples to study the fire retardancy of the paper samples and the fire and decay retardancy of the wood samples. The intern will react the H2O-soluble phosphorus polymers with pulp and wood samples in aqueous solutions and determine how much of the polymers are retained by the pulp and wood samples. The fire retardancy of the paper made from the polymer-reacted pulp and the decay retardancy of the polymer-reacted wood will also be studied.
