TL;DR: In this article, the effects of low-molecular-weight additives, temperature and mechanical action on the structure and properties of starch are discussed, and special attention is given to mixtures of starch with synthetic polymers, e.g., co-polymers of ethylene with vinyl acetate, vinyl alcohol, acrylic acid, cellulose derivatives and other natural polymers.
Abstract: The effects of low-molecular-weight additives, temperature and mechanical action on the structure and properties of starch are discussed. Special attention is given to mixtures of starch with synthetic polymers, e.g., co-polymers of ethylene with vinyl acetate, vinyl alcohol, acrylic acid, cellulose derivatives and other natural polymers. These mixtures can be used in the development of novel environmentally safe materials (films, coatings, packaging materials) and various articles for short-term use. The bibliography includes 105 references.

TL;DR: In this paper, the reversible shape memory polymer (RSMP) by semicrystalline poly(ethylene-co-vinyl acetate) with dynamic covalent polymer networks was reported.
Abstract: This work reports the reversible shape memory polymer (RSMP) by semicrystalline poly(ethylene-co-vinyl acetate) (PEVA) with dynamic covalent polymer networks. The ester linkages in the cross-linked PEVA acted as dynamic covalent bonds in the presence of a transesterification catalyst. This dynamic covalent network imparted the material with good thermal plasticity in a non-flow state at high temperature. The resulting PEVA possessed both the reversible shape memory effect (RSME) and thermadapt property. The thermadapt performance gave little adverse effect on the RSME. This work provides an approach to improve the reprocessability/recyclability of thermoset RSMPs through simple modification of commercially available polymers.

TL;DR: The plasticization approach provides a method for achieving rapid detector response times as well as for producing a large number of chemically different vapor detectors from a limited number of initial chemical feedstocks.
Abstract: Arrays of vapor detectors have been formed through addition of varying mass fractions of the plasticizer diethylene glycol dibenzoate to carbon black−polymer composites of poly(vinyl acetate) (PVAc) or of poly(N-vinylpyrrolidone). Addition of plasticizer in 5% mass fraction increments produced 20 compositionally different detectors from each polymer composite. Differences in vapor sorption and permeability that effected changes in the dc electrical resistance response of these compositionally different detectors allowed identification and classification of various test analytes using standard chemometric methods. Glass transition temperatures, Tg, were measured using differential scanning calorimetry for plasticized polymers having a mass fraction of 0, 0.10, 0.20, 0.30, 0.40, or 0.50 of plasticizer in the composite. The plasticized PVAc composites with Tg 25 °C showed re...

TL;DR: In this article, 2,4-Dichlorophenyl methacrylate and vinyl acetate copolymerized with different feed ratios using dimethyl formamide (DMF) as a solvent and 2,2′-azobisisobutyronitrile (AIBN) as an initiator at 70°C.
Abstract: 2,4-Dichlorophenyl methacrylate (2,4-DMA) and vinyl acetate (VAc) were copolymerized with different feed ratios using dimethyl formamide (DMF) as a solvent and 2,2′-azobisisobutyronitrile (AIBN) as an initiator at 70°C. The copolymers were characterized by infrared (IR) spectroscopy. Copolymer compositions were determined by ultraviolet (UV) spectroscopy. The monomer reactivity ratios were evaluated by the Fineman–Ross method. Average molecular weight and polydispersity index were determined by gel permeation chromatography (GPC), and the intrinsic viscosities of polymers were also discussed. Thermogravimetric analyses of polymers were carried out under a nitrogen atmosphere. The homo- and copolymers were tested for their antimicrobial activity against selected microorganisms. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 895–900, 2003
