Abstract

1,246,678. Polymerized lactones and polyurethanes obtained therefrom. LAPORTE CHEMICALS Ltd. 13 Feb., 1970 [15 Nov., 1968], No. 54368/68. Addition to 1,201,909. Heading C3R. Polyesters are made by polymerizing certain lactones in the presence of an amino or hydroxyl compound as an initiator and a catalyst comprising an organic carboxylic or sulphonic acid having a pKa value less than 2À0 at 25‹ C. and removing the catalyst from the thus formed polyester by absorbing it on to a basic ion exchange resin. The lactones are of a formula where X is -(CR 2 )nwhere n is 4-7, and R is methyl, ethyl, n-propyl, or isopropyl groups or hydrogen, chlorine or bromine atoms. The polyesters may be neutralized by concurrent or subsequent treatment with an acidic ionexchange resin. Polyurethanes are made by reacting the polyester with a polyisocyanate, e.g. di-(4-isocyanatophenyl) methane and an organic compound having at least two active hydrogen atoms bonded to nitrogen or oxygen, e.g. butan-1,4-diol. Reference has been directed by the Comptroller to Specifications 859,645 and 859,642.
