  • Unsaturated polyester resins modified by substitution, with lactic acid, of an acid and alcohol component of the polyester
    Patent number: 9212256
    Abstract: The invention relates to an unsaturated polyester resin comprising a) a lactic acid-modified unsaturated polyester and b) a copolymerizable comonomer, with replacement, with lactic acid, in the composition of an initial polyester, of: i) up to 90 mol % of phthalic anhydride of the acid component of the initial polyester, the acid component comprising from 80 to 20 mol % of maleic anhydride (MA) or fumaric acid, and from 20 to 80 mol % of phthalic anhydride (PA), the polyol component of the initial polyester comprising from 50 to 100 mol % of propylene glycol (PG) and from 0 to 50 mol % of a polyol among ethylene glycol (EG), diethylene glycol (DEG), dipropylene glycol (DPG) and/or 1,3-butylene glycol and/or 1,4-butanediol and/or neopentyl glycol (NPG), ii) up to 100% of a polyol from DPG and DEG, present in an initial overall molar amount ranging up to 50% of the polyol component of the initial polyester and also comprising PG, with the acid component of the initial polyester being maleic anhydride (MA) or f
