Abstract:
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 C 15-25 cyclohydrocarbo 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 C 12-60 hydrocarbo 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 C 5-6 hydrocarbo 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%.

Claim (Index 1):
A low VOC unsaturated alkyd resin P\u2033 obtained by reaction in a process (III) between the following components:\n (A) Optional Component A comprising from 0 to 30% by weight of naturally occurring Rosin, the Rosin comprising from 40 to 80 parts per hundred by weight of Rosin of an unsaturated mono carboxylic acid comprising at least one C 15-25 cyclohydrocarbo moiety capable of undergoing a Diels Alder or Ene reaction; \n (B) Component B comprising from 25 to 80% by weight of a linear C 12-60  hydrocarbo carboxylic acid comprising at least one conjugated ethylenically unsaturated double bond; \n (C) Component C comprising from 1 to 30% by weight of an ethylenically unsaturated C 5-6 hydrocarbo dicarboxylic acid, ester thereof, and/or anhydride thereof, being reactive as a dienophile and/or enophile with Component B and/or Component A where present; \n (D) Component D comprising from 1 to 40% by weight of at least one polyhydric alcohol (polyol); \n (E) Optional Component E comprising at least one monomer other than any of Components A to D; \n the total of Components A to E being 100%; \n to obtain the alkyd resin P\u2033 and wherein the alkyd resin P\u2033 obtained from the process (III) has: \n (i) an acid value of no more than 50 mg KOH per g of the solid alkyd resin; \n (ii) a number average molecular weight (M n ) of at least 1200 g/mol; \n (iii) an oil length less than or equal to 78; and \n (iv) optionally a renewable content of at least 50% by weight of components (A) to (E) where present; and wherein \n low VOC denotes that the total amount of organic compounds that have a boiling point from 50 to 250\u00b0 C. that are present in the composition is less than 100 g/l.
