Triphenylmethyl methacrylate (TrMA) is a unique monomer that forms an
isotactic polymer, PTrMA, even by a radical process, (11) which usually yields atactic or syndiotactic polymers.
We used commercial
isotactic polypropylene (PP) Basel Moplen HP456J as a matrix material.
Key statement: Disclosed is an ethylene-propylene-diene terpolymer having
isotactic polypropylene crystallinity compounded with a blend rubber wherein the terpolymer can be present in an amount effective to improve tack, aged tensile strength retention, fatigue resistance, ozone cracking resistance and reversion resistance.
At earlier stage (1h) of the reaction, molar ratios of
isotactic (mm), atactic (mr), and syndiotactic (rr) pHEMA were 39, 13, and 48 mol%, respectively (Table 1).
In contrast, an
isotactic stereoblock (bottom) polymer has a higher melting point.
