  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%。

  [EN] The present invention relates to polyurethane polymers comprising as part of its polymer backbone biobased ?-hydroxyfatty acids or derivatives thereof, processes for the preparation thereof, and compositions thereof having improved properties. The polyurethanes of the present invention are prepared from copolyester prepolymers comprising the biobased ?-hydroxyfatty acids that may also contain additional components that can be selected from aliphatic or aromatic diacids, diols and hydroxyacids obtained from synthetic and natural sources. The biobased ?-hydroxyfatty acids that comprise the polyurethanes and copolyester prepolymers of the present invention are made using a fermentation process from pure fatty acids, fatty acid mixtures, pure fatty acid ester, mixtures of fatty acid esters, and triglycerides from various sources. The copolyester prepolymers of the present invention may contain various amounts and types of ?-carboxyfatty acids depending on the engineered yeast strain used for the bioconversion as well as the feedstock(s) used.
  [FR] La présente invention concerne des polymères de polyuréthane comprenant en tant que partie de leur squelette de polymère des ?-hydroxyacides gras ou des dérivés de ceux-ci, des procédés pour la préparation de ceux-ci, et des compositions de ceux-ci ayant des propriétés améliorées. Les polyuréthanes de la présente invention sont préparés à partir de prépolymères de copolyester comprenant les ?-hydroxyacides gras d'origine biologique qui peuvent également contenir des composants additionnels qui peuvent être choisis parmi des diacides, diols et hydroxyacides aliphatiques ou aromatiques obtenus à partir de sources synthétiques et naturelles. Les ?-hydroxyacides gras d'origine biologique qui comprennent les polyuréthanes et les prépolymères de copolyester de la présente invention sont préparés en utilisant un procédé de fermentation d'acides gras purs, de mélanges d'acides gras, d'ester d'acide gras pur, de mélanges d'esters d'acide gras, et de triglycérides de différentes sources. Les prépolymères de copolyester de la présente invention peuvent contenir différentes quantités et différents types de ?-carboxyacides gras suivant la souche de levure modifiée utilisée pour la bioconversion ainsi que la/les matière(s) première(s) utilisée(s).
