  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%。

  Rosin modified phenolic resins are prepared by reacting together resin acid, fatty acid, tri- or higher-functional phenolic compound and aldehyde. The fatty acid may be Monomer (derived from the fatty acid dimerization process). The reaction mixture may optionally include a,I3-olefinically unsaturated carbonyl compounds and/or polyol. The resin may be dissolved in a solvent to form a varnish. The resin may be used as a component of printing inks, e.g., inks for lithographic or gravure printing.

  Adhesive compositions and articles that contain these adhesive compositions are described. More particularly, the adhesive compositions include (a) a block copolymer prepared from monoethylenically unsaturated monomers and (b) a tackifier mixture. The adhesives compositions can be adhered to many substrates including those having a non-polar surface.
