Claims
- 1. A terpolymer of ethylene prepared by a high pressure polymerization process, having a melt flow index of from 50 to 500 g/10 min and a Shore A hardness according to German Industrial Standard (DIN) 53,505 of 20 and which is soluble or swellable in an aqueous medium, comprising
- a) from 40 to 60 parts by weight of ethylene,
- b) from 2 to 40 parts by weight of a (meth)acrylate,
- c) from 1 to 40 parts by weight of an .alpha.-.beta.-ethylenically unsaturated carboxylic acid, a carboxylic anhydride or a carboxamide and
- wherein the (meth)acrylate (b) is an .omega.-alkyl-, -cyclo- alkyl- or -aryl-poly-(alkylene oxide-.alpha.-yl (meth)-acrylate of the formula (I) ##STR6## where R.sup.1 is H or CH.sub.3, R.sup.2 is alkyl, cycloalkyl or aryl and m and n are each equal to or greater than 0, with the proviso that the sum of m and n is always equal to or greater than 2.
- 2. A terpolymer as defined in claim 1, wherein, in the (meth)acrylate of the formula (I), m is from 2 to 100 and n is from 0 to 100.
- 3. A terpolymer as defined in claim 1, wherein, in the (meth)acrylate of the formula (I), m is from 2 to 50 and n is from 0 to 50.
- 4. A terpolymer as defined in claim 1, wherein, in the (meth)acrylate of the formula (I), R.sup.2 is CH.sub.3, C.sub.2 H.sub.5, C.sub.3 H.sub.7, C.sub.4 H.sub.9, C.sub.16 H.sub.33, C.sub.6 H.sub.11 or C.sub.6 H.sub.5.
- 5. A copolymer as claimed in claim 1 wherein component C) is from 8 to 30 parts by weight of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, a carboxylic anhydride or a carboxamide.
- 6. A copolymer of ethylene as claimed in claim 5, which contains from 8 to 30 pars by weight of acrylic acid or methacrylic acid as copolymerized units.
