A new photochemical synthesis of block copolymers is described. Polyesters are prepared containing γ-keto pimelic acid. This provides ketone carbonyl functions along the backbone of the polymer chain. When irradiated with ultraviolet light in the pr

Photozymes are novel water-soluble polymers made by the copolymerization of mixtures of hydrophobic and hydrophilic monomers, some of which contain chromophores capable of absorbing light and transmitting the excitation energy to selected traps by me

A novel synthetic route for the preparation of photodegradable poly(ethylene terephthalate) is described, along with procedures for the synthesis of 14C-labeled plastic. Studies of the labeled plastic in burial tests in active soil show that signific

The radical copolymerization of 2-(6-sulfo-2-naphthoxy)ethyl methacrylate sodium salt and lauryl methacrylate led to a water-soluble polymer that contained both hydrophobic and hydrophilic components. Studies showed that naphthalene excimer formation

Inverse gas chromatography (INC) was used to study the thermal transitions in the organic liquid-crystalline polyester [COPhO(CH 2 ) 10 OPhCOOPhO(CH 2 ) 10 OPhO] n . A crystal-to-nematic and a nematic-to-isotropic transition were detected, as was a l

Random copolymers ranging from 0 to 27 % in β-hydroxyvalerate content were studied. While X-ray data indicated that the crystallinity remained at about 60 % throughout this composition range, DSC and density data indicated a substantial reduction. T

It is shown that rigorous analysis of poly[(10-phenyl-9-anthryl) methyl methacrylate] fluorescence decays recorded under magic angle sampling conditions following. Synchrotron Radiation pulsed excitation reveals that the excited-state decays are not

As a result of the experimental work summarized in this review the value of the gas chromatographic method for studying polymers seems to be well established. Surface and bulk properties of polymers can be measured both from a thermodynamic and kinet
