High density polyethylene tapes and fibres have been grafted with ally1 alcohol by vapour phase radiation-induced graft polymerization. Grafting was confirmed by FTIR, XPS and a dye assay. The ratio of surface to bulk grafted hydroxyl groups was higher for gel spun fibre as compared to natural draw
## Abstract The effect of recycled PP on incompatible blends of virgin polypropylene (PP) and highโdensity polyethylene (HDPE) was studied. Recycled PP from urban solid waste was extracted with methyl ethyl ketone and the compatibilizing action of the product before and after extraction was examine
## Abstract Highโdensity polyethylene grafted isotactic polypropylene (PPโ__g__โHDPE) was prepared by the imidization reaction between maleic anhydride grafted polyethylene and amineโgrafted polypropylene in a xylene solution. The branch density was adjusted by changes in the molar ratio between ma
## Abstract Polyethylene (PE) and polypropylene (PP) were reacted with benzoyl peroxide (BPO) and 2,2,6,6โtetramethylโ1โpiperidinyloxy (TEMPO) to prepare PEโTEMPO and PPโTEMPO macroinitiators, respectively. Molecular weight of PP decreased, whereas that of PE increased during the reaction with the
