Abstract: A method of collecting secretions from trees including making a predetermined shaped incision through the bark to the surface of the wood and applying a secretion flow activation agent to the incision. The method further includes placing a receptacle in the incision, wherein the receptacle comprises a lower outer part and a flow tube portion located at the lower outer part, and wherein a portion of the receptacle has the same shape as the predetermined shape of the incision. The method further includes fixing a collecting apparatus to the flow tube and subsequently removing the collecting apparatus from the flow tube when the collecting apparatus contains secretions from the trees.

Abstract: This invention relates to a process for the preparation of improved terpene-phenol resins particularly useful in the field of adhesives, comprising:A. reacting 1 molar proportion of a phenol having at least 2 reactive sites with 0.4-0.6 molar proportion of a carene, in the presence of an acidic condensation catalyst;B. reacting the reaction product obtained in step (a) with 0.4-0.6 molar proportion of said carene in the presence of said catalyst, andC. subsequently reacting the material obtained in step (b) with a reactive terpene, the molar ratio between said reactive terpene and the amount of carene added in step (b) being comprised between 0.5 and 5.
