Abstract

1,212,351. Polymerizing lactones in the presence of preformed polymers. LAPORTCHEMICALS Ltd. 14 Aug., 1968 [17 May, 1967], No. 22871/67. Headings C3P and C3R. A lactone of formula where n is 3-6, R is H, Me, Et, n-Pr, iso-Pr, Cl or Br, and wherein the total number of carbon atoms in all the R groups does not exceed 12 and the total number of halogen atoms in all the R groups does not exceed 2 is polymerized in the presence of a preformed polymer which has at least one alcoholic-OH group and is (a) an unsaturated polyester having two or more ethylenic double bonds per molecule, (b) a ketone formaldehyde resin or (c) a ketone methanol resin. Specified lactones are epsilon caprolactone and methyl epsilon caprolactone or mixtures thereof. Specified for (a) are polyesters of ethylene glycol, diethylene glycol, propylene glycol and dipropylene glycol with maleic acid or anhydride. Specified ketones for (b) are cyclohexanone or alkyl derivatives thereof, cyclopentanone or alkyl derivatives thereof, methyl ethyl ketone or diethyl ketone. Specified ketones for (c) are cyclohexanone, cyclopentanone or alkyl derivatives thereof. Catalysts, e.g. HC1, H 2 SO 4 , H 3 PO 4 , CH 3 CO 2 H, CCl 3 CO 2 H, CF 3 CO 2 H, ZnCl 2 , Zn 3 (BO 4 ) 2 , dibutyl tin oxide or hexylene glycol titanate may be used. The examples disclose polymerization of epsilon caprolactone with (1) maleic anhydrideethylene glycol polyester, (2) cyclohexanoneformaldehyde resin and (3) cyclohexanonemethanol resin. The final unsaturated polymers may be cured with a vinyl monomer, e.g. styrene, methyl methacrylate or diallyl phthalate. . Reference has been directed by the Comptroller to Specification 859,642.
