Surface modification of polyolefins by photografting of acrylic monomers
Macromolecular Symposia, 1998AbstractHigh‐speed surface modification of polypropylene (PP) and polyethylene (PE) films has been achieved by liquid phase photograft polymerisation of acrylic acid (AA) and hydroxypropyl acrylate (HPA). Benzophenone was used as photoinitiator to generate polymer radicals at the surface of the polyolefin film.

Self‐Initiated Photopolymerization and Photografting of Acrylic Monomers
Macromolecular Rapid Communications, 2004AbstractSummary: This work demonstrates that acrylic acid (AA), glycidyl acrylate (GA) and several other acrylic monomers can be photopolymerized and photografted onto high‐density polyethylene (HDPE) by self‐initiation. The self‐initiation mechanism of these acrylic monomers is possibly by an excitation of the monomer to a triplet state (T3) with ...

Photografting polymerization of polyacrylamide on PHBV films (I)
Journal of Applied Polymer Science, 2007AbstractPhotografting polymerization of polyacrylamide (PAM) onto poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) films using benzophenone as photoinitiator was studied. The morphology and structure of the grafted PHBV film were characterized by Fourier transformed infrared spectroscopy (FTIR) with attenuated total reflectance (ATR) and scanning ...

The role of far UV radiation in the photografting process
Polymer Bulletin, 1996With low density polyethylene (LDPE) film as substrate, polyethyleneterephthalate (PET) film as filter, and an high pressure mercury (HPM 15) lamp as UV radiation source, the function of far UV radiation was examined. The results show that when the far UV (200–300 nm) was eliminated, the rate of polymerization of acrylic acid in the interlayer between ...

“Surface‐photografting”: new applications to synthetic fibers
Polymers for Advanced Technologies, 1994Abstract“Surface‐photografting” with UV‐irradiation of polypropylene (PP) fiber and film and high‐strength polyethylene (HSPE) yarn has been made with acrylic acid (AA) and acrylamide (AM) as monomers and benzophenone (BP), 4‐chlorobenzophenone (4‐BCP) and hydroxylcyclohexylacetophenone (HHA) as photoinitiators using a new continuous method.

Surface photograft polymerization on segmented polyurethane using the iniferter technique
Journal of Biomedical Materials Research, 1999A segmented polyurethane (SPU) film was chloromethylated and subsequently dithiocarbamated. The treated films were immersed in solutions containing poly(ethylene glycol) methacrylate (PEGMA) or N, N-dimethyl-acryl amide (DMAAm) and irradiated with ultraviolet (UV) light. The resultant surfaces were highly wettable with water.

Photografted Poly(ethylene glycol) Matrix for Affinity Interaction Studies
Biomacromolecules, 2006A poly(ethylene glycol) (PEG)-based matrix for studies of affinity interactions is developed and demonstrated. The PEG matrix, less than 0.1 microm thick, is graft copolymerized onto a cycloolefin polymer from a mixture of PEG methacrylates using a free radical reaction initiated by UV light at 254 nm.

Preparation of imprinted membranes by photograft polymerisation
2006Molecular imprinting has entered in different fields with particular attention in chemistry, biochemistry, biotechnology and medicine. This technology, firstly proposed by Wulff in 1972 [1], is a method to introduce molecular recognition sites for a given interesting molecule into a polymeric material during its preparation.
