Methacrylic acid (MA) was graft polymerized onto starch using Ce 4/ initiator in aqueous medium. The dependence of grafting on the reaction variables, such as monomer and initiator concentration and time and temperature, was studied in detail. Acid hydrolysis and infrared (IR) spectroscopy were used
## Abstract Hydrophilic polyolefin materials were prepared by grafting tBA from PE macroinitiators bearing functionalized norbornene units capable of initiating an ATRP. This method produced semicrystalline graft copolymers (PE__‐graft‐__PtBA) with narrow molecular weight distributions (1.2–1.4) an
