Abstract
Official abstract text for this publication.
The invention thus provides terpolymers of ethylene, at least one ethylenically unsaturated ester and propene, which have i) from 4.0 to 12.0 mol % of structural units derived from at least one ethylenically unsaturated ester having a C 4 - to C 20 -alkyl radical, ii) from 0.5 to 4.0 methyl groups derived from propene per 100 aliphatic carbon atoms, and iii) fewer than 8.0 methyl groups stemming from chain ends per 100 CH 2 groups.
First claim
Opening claim text (preview).
The invention claimed is: 1. A terpolymer consisting of ethylene, propene, i) from 4.0 to 12.0 mol % of structural units derived from at least one ethylenically unsaturated ester, wherein the at least one ethylenically unsaturated ester is selected from the group consisting of ethylenically unsaturated esters having a C 4 - to C 20 -alkyl radical, and ii) up to 3 mol % of structural units derived from an ethylenically unsaturated ester with a short alkyl chain having from 1 to 3…
