  Low VOC, unsaturated alkyd resins are obtained by reacting (A) to (E): (A) optionally from 0 to 30% w/w naturally occurring Rosin, comprising from 40 to 80 w/w parts per hundred of Rosin of an unsaturated mono carboxylic acid with at least one C15-25cyclohydrocarbo moiety capable of a Diels Alder or Ene reaction (preferred monoacids being abietic acid, palustric acid, levopimaric acid, sandaracopimaric acid, and/or anhydrides thereof); (B) from 25 to 80% w/w of a linear C12-60hydrocarbo carboxylic acid with at least one (preferably at least two conjugated) C═C bonds (=unsaturated fatty acid); (C) optionally from 1 to 30% w/w of an ethylenically unsaturated C5-6hydrocarbo dicarboxylic acid and/or anhydride thereof, being reactive as a dienophile and/or enophile with A and/or B (preferred for C are itaconic acid, citraconic acid and/or anhydrides thereof); (D) from 1 to 40% w/w of at least one polyol; (E) optionally at least one monomer other than A to D—the total of A to E being 100%. There is a further optional step (II) where more or new (C) may be blended with the alkyd resin; the amount of C in blend being from 1 to 30 parts w/w of 100 parts of monomers (A) to (E)—and where (C) is at least used as a monomer and/or as a diluent in the blend and where alkyd resin (i) has acid value of <50 KOH/g of alkyd; (ii) Mn of >=1200 g/mol (iii) oil length <80; (iv) optionally biorenewable content >=50%.

  将(A)至(E)反应可获得低挥发性有机化合物的不饱和醇酸树脂：(A) 0% 至 30% w/w 的天然松香，其中包括 40% 至 80% w/w 的不饱和一元羧酸（松香中至少有一个 C15-25 环氢羧基能够发生 Diels Alder 或 Ene 反应）（优选的一元酸为阿比特酸、棕榈酸、左旋庚二酸、沙拉庚二酸和/或其酸酐）；(B) 25% 至 80% w/w 的线性 C12-60 羧酸，至少有一个（最好至少有两个共轭）C═C 键（=不饱和脂肪酸）；(C) 1-30%重量比的乙烯不饱和 C5-6 氢羧酸和/或其酸酐，作为亲二烯和/或亲 烯物与 A 和/或 B 反应（C 的优选物为衣康酸、柠康酸和/或其酸酐）； (D) 1-40%重量比的至少一种多元醇； (E) 除 A 至 D 之外的至少一种单体--A 至 E 的总和为 100%。还有一个可选步骤 (II)，在该步骤中，可将更多或新的 (C) 与醇酸树脂混合；C 在混合物中的用量为 100 份单体 (A) 至 (E) 中的 1 至 30 份 w/w，其中 (C) 至少用作混合物中的单体和/或稀释剂，醇酸树脂 (i) 酸值 =1200 g/mol (iii) 油长 =50%。

  The application of raw wood material from a tree of the genus Larix for treatment and prophylaxis of inflammation in humans or animals is described. The present invention is based on the use of raw larch wood material as a medicament and an anti-inflammatory food/feed supplement for animals and humans, wherein preferably larch sawdust, a by-product of wood industry, is used.
