Abstract

1,144,240. Copolymers and graft copolymers. AGFA-GEVAERT A.G. 19 Dec., 1966 [22 Dec., 1965], No. 56675/66. Headings C3G and C3P. [Also in Division G2] In a series of preparations (1-4), polyethylene glycols having molecular weights ranging from 1000 to 12,000 are esterified with acrylic acid chloride and the unsaturated ester obtained is copolymerized with acrylic acid in the presence of potassium persulphate; in further preparations (5), a dodeca-ethylene glycol monoalkyl ether, in which the alkyl groups have 16-18 carbons, having a molecular weight of about 1500 is esterified with acrylic acid chloride and copolymerized with acrylic acid, and (6) a polyethylene glycol of molecular weight 4000 is esterified with acrylic acid chloride and then copolymerized with sodium vinyl sulphonate. A graft copolymer is prepared in a further preparation (7) by polymerizing methacrylic acid in the presence of a polyethylene glycol of molecular weight 4000.
