Poly(2-isopropyl-2-oxazoline) (PiPrOx), known as thermoresponsive pseudopeptide, exhibits a phase transition in aqueous solution at a temperature near human body temperature and is nontoxic to many cell lines. These facts make this polymer potentially attractive for many bioapplications. PiPrOx is similar in chemical structure to poly(N-isopropylacrylamide) (PNIPAM) and is considered as the alternative to this so-called “gold standard” thermoresponsive polymer, however significant differences in properties of these two polymers are worth attention. To control the properties, that directly translate into application possibilities, iPrOx was copolymerized with a wide range of different monomers, and, optionally, the obtained copolymers have been variously modified. This review summarizes the few-years-back research accomplishments and progress in studies on PiPrOx and iPrOx-based copolymers. Considering the recent developments, the properties of iPrOx-based (co)polymers are shown, aiming at promoting their great potential in the biomedical field. Having gathered the information on modification possibilities, structure-property relationship and applications, especially in the biomedical field, a bit of speculation on the future prospects of iPrOx-based (co)polymers is given.","PeriodicalId":20326,"journal":{"name":"Polymer Reviews","volume":"135 1","pages":"529 - 548"},"PeriodicalIF":13.1,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80484235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rational design was achieved in metathesis, addition, and CANAL polymers as an extension of the modular strategy using norbornene motifs as building blocks. Tuning the structure of norbornene-containing monomer units allowed obtaining high-free-volume polymers with apparent Brunauer–Emmett–Teller (BET) surface areas up to 1000 m2/g that made these materials promising for various engineering applications such as membrane gas separation, gas sorbents, CO2 capture, scaffolds to support catalysts, or reagents for catalysis.

Among the various energy storage devices, solid-state dielectric capacitors possess the advantage of high-power density which makes them highly attractive for pulsed power applications. Polymers are particularly suitable for dielectric energy storage applications because of their high breakdown strength, low dielectric loss, formability, self-healing capability, flexibility, solvent processability, and graceful breakdown failure. Strategies to enhance the dielectric breakdown strength of polymeric dielectric capacitors are emphasized in this review. General background on breakdown mechanism, breakdown characteristics, and factors influencing polymer dielectrics breakdown are introduced. Given that polymers have low permittivity, strategies to substantially enhance dipole mobility and hence the permittivity, are highlighted. We discuss strategies to address permittivity contrast between nanofillers and the polymer matrix including the potential for developing gradient permittivity structured nanofillers. To improve the compatibility of nanofiller with polymer and minimize nanofiller aggregation, different routes to surface functionalize nanoparticles are presented. An outlook and future perspectives section are provided for the design of high energy density polymer film capacitors.","PeriodicalId":20326,"journal":{"name":"Polymer Reviews","volume":"149 1","pages":"211 - 260"},"PeriodicalIF":13.1,"publicationDate":"2021-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79442795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chemical modification using multifunctional epoxide styrene-acrylic chain extenders (CE) in reactive processes is by now an established method to prevent degradation and to improve the process ability as well as the final properties of thermoplastics. One of the most common representatives of these CE is better known under its trade name Joncryl®. Since several years ago, Joncryl® ADR owes an ever-growing importance in industry and academia. It can be applied as reactive melt modifier for numerous polymers, mainly polyesters, where it largely affects the rheological properties and the thermal behavior. This review focuses on the reactive behavior of Joncryl® ADR as well as the induced changes in the rheological behavior of the polymers caused by this modification. The Joncryl® ADR incorporation leads to an increased shear viscosity, a higher melt strength and induces strain hardening due to the formation of branched chains and/or even crosslinking. The crystallization is also directly influenced by the changed chain topology. Eventually, this review article extensively addresses the benefits of using Joncryl® for processing such as stabilization, recycling, foaming, and polymer blending.

Tough, their unique properties are mainly governed by reinforcing fillers such as carbon black and silica. However, the reinforcing power is not only driven by the chemical nature of fillers but also by their particle size, shape, distribution and dispersion. In order to minimize agglomeration and processing difficulties, the idea of in situ generated fillers has been approached. In situ means “locally” and refers to the generation of fillers during the vulcanization process. This versatile technique provides individual tailoring of rubber compounds due to numerous possible reaction pathways. In situ reinforcement has been reported for all relevant rubber matrixes and is already employed commercially. In this review, a comprehensive overview of possible in situ reinforcing strategies for organic rubbers and their impact on mechanical properties is provided. It covers the reinforcing power of sol–gel derived in situ fillers, metal salts of unsaturated carboxylic acids as well as the formation of interpenetrating networks with resins in detail.
