✦ Synopsis

Abstract

2‐Phenyl‐1,3‐oxazoline was injected into poly(ethene‐co‐methacrylic acid), containing 4,25 mol‐% methacrylic acid units, at 225°C. In the first stage, 2‐phenyl‐1,3‐oxazoline reacted with carboxylic acid groups to form esteramide side chains via grafting reaction. In the second stage, 2‐phenyl‐1,3‐oxazoline containing methyl 4‐nitrobenzensulfonate initiator was added to initiate in‐situ cationic polymerization, yielding poly(N‐benzoylethylenimine) as dispersed phase with 0,2–3,5 μm average diameter. Morphological, mechanical and thermal properties of poly‐(ethene‐co‐methacrylic acid) blends, prepared by grafting combined with in‐situ polymerization of 2‐phenyl‐1,3‐oxazoline, were investigated.

## Abstract A novel family of functional ethene copolymers with various side chains were prepared by melt grafting of poly(ethene‐__co__‐methacrylic acid), containing 3,00 and 4,25 mol‐% of methacrylic acid, with 2‐substituted 1,3‐oxazolines such as 2‐phenyl‐1,3‐oxazoline, 2‐undecyl‐1,3‐oxazoline,
