Plant Resins: Chemistry, Evolution, Ecology, and Ethnobotany
Journal of the American Institute for Conservation, 2004Few people are aware of the great diversity of resin-producing plants or the remarkable roles resins play for plants and people. Resins evolved millions of years ago to defend plants against their enemies, as recorded by fossil resins like amber, and ...

Defensive Use by an Insect of a Plant Resin
Science, 1974Larvae of the sawfly Neodiprion sertifer (Hymenoptera: Diprionidae), when disturbed, discharge an oily oral effluent essentially identical chemically to the terpenoid resin of its host plant ( Pinus sylvestris ).

Biorenewable Epoxy Resins Derived from Plant-Based Phenolic Acids
, 2016Plant-derived phenolic acids are attractive substitutes for petroleum sources for the derivation of polymers, due to their rigid aromatic rings and chemical groups amenable to functionalization.

Pigment & Resin Technology, 1983
The resin plant user and designer have a joint responsibility to provide reliable process plants, conserve energy and maintain the highest degree of safety. With this in mind Hygrotherm for many years has been designing and building resin plants for installation world‐wide. They have covered a wide range of products and operating conditions.

Separation of plant polyphenolics by chromatography on a boronate resin
Journal of Chromatography A, 1981m-Aminophenylboronic acid attached to polyacrylamide beads by a short aliphatic chain strongly and selectively binds vicinal dihydroxyphenyl substituted compounds at pH 7–8. At lower pH these substances are released quantitatively thus affording a simple and rapid method for separation and purification of catecholic materials.

Deuterium exchangeability in modern and fossil plant resins
Geochimica et Cosmochimica Acta, 2018Abstract Deuterium exchange experiments on modern and fossil plant resins (amber) were conducted to assess to what extent diagenetic alteration can overprint the stable hydrogen (δ2H) and carbon (δ13C) isotopic composition of these materials. Pairs of resins and amber fragments were placed together with deuterated water in sealed quartz-glass tubes ...

Composites from Northern Red Oak (Quercus robur) Leaves and Plant Oil-Based Resins
, 2013Composite materials were successfully made out of plant oil-based resin and northern red oak (Quercus robur) leaves col- lected in the fall. The viscosities of the bio-based resins (MAESO and MAELO) were suited to high temperature resin transfer mold ...
