摘要：This paper presents the results of studies employing Cuban pine oleoresin in its natural state, as a substitute for traditional rosin as raw material for obtaining specific chemical additives. The applications include three varieties of paper sizing, tensides and specialized lubricants. Technical-economical considerations related to the practical introduction of these products also are considered
