This study investigates the role of social networks in influencing individuals' decision whether to participate a community energy initiative (CEI), by incorporating different types contact between members and CEI initiators. Engagement is crucial for success thus key question how initiators can reach stimulate involvement. By analyzing community's network we investigate structure ties influenc...

Three new triphenylamine derivatives bearing formyl groups were synthesized and tested for their suitability as photo-initiators multi-photon lithography. The efficiency of the photo-polymerization was by two different setups a variety applications. Based on broad fabrication window, well-defined 3D prints in sub-micron range (resolution aspect ratio), solubility, we demonstrate these are viabl...

It is well known that well-defined polyacrylonitrile (PAN) with high molecular weight (Mw > 106 g ̈mol ́1) is an excellent precursor for high performance carbon fiber. In this work, a strategy for initiators for a continuous activator regeneration atom transfer radical polymerization (ICAR ATRP) system for acrylonitrile (AN) was firstly established by using CuCl2 ̈ 2H2O as the catalyst and 2,21-az...

A new strategy for synthesizing well-defined, chain-end-functionalized polymers containing multiple hydrogen-bonding (MHB) groups capable of heterodimerization in both solution and the melt has been developed. Two complementary MHB systems were chosen for initial studies: 2-ureido-4[1H]-pyrimidinone (UPy) and 2,7diamido-1,8-naphthyridine (Napy) and ATRP initiators containing either UPy or Napy ...

Aimed to obtain a type of oil displacement with both surface activity and polymer performances, this paper based on mixing initiators at low temperatures, prepared a type of anion–nonionic surface–active polymer oil displacement agent (ANSP–1) by introducing polymerizable anion–nonionic surfmer (ANS–1), acrylamide (AM) and acrylic acid (AA). Structure of ANSP–1 was measured by FTIR. Laboratory ...

A novel method based on in situ surface polymerization of methyl methacrylate (MMA) has been developed for the rapid fabrication of poly(methyl methacrylate) (PMMA) capillary electrophoresis (CE) microchips. MMA containing both thermal and ultraviolet (UV) initiators was allowed to prepolymerize in a water bath to form a fast curing molding solution that was subsequently sandwiched between a ni...

The kinetics of radical-scavenging activities for colchicine and tropolone remain unknown. Their antioxidant activities were determined by the induction period (IP) method in the polymerization of methyl methacrylate initiated by thermal decomposition of 2,2'-azobisisobutyronitrile (AIBN, R*) or benzoyl peroxide (BPO, PhCOO*) using differential scanning calorimetry (DSC) under nearly anaerobic ...

The objective of this paper is to present a dynamic Monte Carlo model that is able to simulate the polymerization of styrene with bifunctional free-radical initiators in a batch reactor. The model can predict the dynamic evolution of the chain length distribution of polystyrene in the reactor. The model includes all relevant polymerization mechanistic steps, including chemical and thermal radic...

The synthesis of original co-telomers based on 3,3,3-trifluoropropene (TFP) and vinylidene fluoride (VDF) with a general formula: RF-[CH2-CF2]n-[CH2-CH(CF3)]m-I (where n=1-63, m=2-640, and RF=(CF3)2CF) was achieved by sequential and random cotelomerizations in the presence of RFI. The radical cotelomerizations were initiated by thermal decomposition of different peroxide and persulfate initiato...
