“…Chlorinated polyethylene (CPE) blends with different polymers have been reported for many purposes such as improvements in the toughening properties of host polymers , as a compatibilization agent through enhancement of interfacial interactions between two polymers , improved processing properties , ameliorated adhesion properties , enhanced ignition resistance properties , and modified gas transport properties . Based on the percentage of chlorination of the polymer, there are many classifications of CPE ranging from plastic (0–14%), thermo‐elastoplast (15–30%), elastomer (31–46%), rigid polymer (47–61%), to friable resin (62–73%) . Maksimov et al blended CPE with 36 % chlorination content with high‐density polyethylene (HDPE) and low‐density polyethylene (LDPE) .…”

Blends of high-density polyethylene (HDPE) with chlorinated polyethylene (CPE) were generated using melt mixing. CPE of two different chlorination contents was used and its amount in the blends was varied from 1% till 30%. The rheological, thermal, mechanical, and morphological properties of the blends were characterized along with miscibility analysis. In general, better mixing of the CPE polymer in HDPE was observed at lower CPE concentration and reduced mixing or immiscibility occurred at higher concentration of CPE. However, the extent of immiscibility was different in both CPE25 and CPE35 systems. The rheological analysis of the data using Cole-Cole, Han-Chuang and van Gurp plots confirmed the miscibility of CPE25 blends (except for 30% CPE25 blend at lower frequency) whereas CPE35 blends with 10-30% CPE content were immiscible. Highest increase in the rheological properties (complex moduli) was observed at 2% CPE content. The mechanical properties of the CPE25 blends were superior than the corresponding CPE35 blends especially at higher CPE concentration where effects of immiscibility as well as matrix plasticization played a role. The morphology characterization using TEM indicated change in the crystalline features of the polymer in the case of CPE35 blends. The optical microscopy also confirmed the better mixing of CPE25 polymers in HDPE than CPE35. The CPE25 blends exhibited uniformly dispersed CPE phase which was also confirmed by the rheological analysis. However, the blends of CPE35 with 10% CPE content onwards had significant phase immiscibility. POLYM. ENG. SCI., 54:85-95, 2014. 10% CPE35, (m) 15% CPE35, (n) 20% CPE35, and (o) 30% CPE35 blends.

“…The need to assemble , thermally , and chemically robust , materials has led to the development of numerous controlled assembly methods. The assembly of materials into predictable thickness layers employing a layer-by-layer scheme − results in a higher levels of control over the properties of the resulting polymer when compared to other bulk preparation methods.…”

Controlled Assembly of Silane-Based Polymers: Chemically Robust Thin-Films

et al. 2010

We describe the controlled assembly of silane-based copolymers on various interfaces that have surface silanol groups. This assembly occurs as a result of the formation of very robust siloxane bonds (Si-O-Si) due to a condensation reaction between the alkoxysilane groups of the polymers and surface hydroxyl groups of the substrates. Deposition of these copolymers is not self-limiting; therefore, they could not be assembled into discrete monolayers. However, UV-visible data collected as a function of deposition cycle reveals a linear relationship, confirming the deposition of a constant amount of polymer in each deposition cycle. A linear variation of layer thickness with deposition cycles is also observed. The assembled polymer layers are found to be very robust and resistant even when exposed to piranha solution for several hours.
