Using PVA as a structural adhesive puts the safety of home owners and
fire fighters at risk as there is a higher probability of creep and sudden collapse of wood

...
The melt compounding of
thermoplastic polymer was observed to produce better silicate dispersion and improved
polymer intercalation efficiency over the solvent casting method
...
The materials used was Ethyl Vinyl Acetate (EVA), which is a
thermoplastic copolymer and solid at room temperature

The
samples were prepared by melt compounding the EVA copolymer with different ratios of
organo-MMT nanofiller (0, 1, 3, and 5 wt%) using internal mixer (brabender plasticoder)
...
%) using twin screw extruder
...
In contrast,
the melt compounding process of EVA copolymer using twin screw extruder resulted in best
mechanical performance at high filler loading (5wt%)
...
Ethylene vinyl acetate copolymers (EVA) are randomly structured polymers, which
offer excellent ozone resistance, weather resistance, and excellent mechanical
properties
...
According to Hemmati et al (2014), blending polymeric materials is a well establish
method to enhanced ultimate properties of material
...
For example the semi-crystalline binary blends of polyethylene
(PE)/ethylene-vinyl
...
Other industrial appli- cations of these blends include wire and
cable-insulation coatings and foams
...

Garmabi, & Modarress, 2014)

...
According to Camargo et al, a
different behaviour on DMA properties is observed when blending copolymers, such as
the symmetric styrene-butadiene- styrene [SBS] block copolymers, are previously used
to modify the matrix
...
In this material, a large
improvement of the storage modulus at 25 °C was observed
...
Müller et al (2017) observed behavior of phase separated block copolymers and polymer
blends
...
If the space is so narrow, that the spherulitic growth is
restricted, primary nuclei are not available for heterogeneous crystallization
...
This can lead to a low crystallization
rate, degree of crystallinity and melting point
...
This is the

...
One solution to address this, is the additivation by

graft or block copolymers
...
Incorporation of nanoparticles even prevented the coalescence
after shear mixing
...
Another explanation might be that nanoparticles behave
like graft or bloc copolymers, which accumulate at the interface and are bound by
physical or chemical interactions
...

Electro-hydrodynamic
techniques
(electrospinning
and
electrospraying) have also been used to create superhydro/oleo/amphiphobic surfaces
...
By tuning the
electrospinning parameters, post-treatments steps or using some additives in the
polymer solution, the second scale of roughness needed for superhydrophobicity is
created
...

...
Then the welldispersed MWCNTs reinforced UPR nanocomposites were fab- ricated through solvent
evaporation
...
The stimulation of free radicals in UPR occurs by either heat or the
presence of a catalyst, thereby transforming resin from liquid state to cross- linked solid
state through exothermic reactions
...
Ethylene vinyl acetate copolymers (EVA) are one of the important engineering
polymers with broad applications, such as hot melt adhesives, packaging, wire and cable
insulation and carpeting
...
Shi et al (2009) studies ways to enhance flamer
retardant EVA copolymers
...
A cationic vinyl acetate copolymer rather than a small
molecule was used as the surface modifier to make the masterbatch, which was then
mixed with EVA to yield well exfoliated nanocomposites
...
The material was purchased from
Southern Clay Products
...
The masterbatch
nanocomposite was completely exfoliated as a result of the strong electrostatic
interactions of the pendant cationic ammonium groups in the copolymer with the anionic
silicate surface
...
(Shi et al
...
Ethyleneevinyl acetate copolymer (EVA) is a widely used material, particularly as a
zero-halogen material in the cable industry
...
Since the
nanoclay incorporation is also believed to assist the formation of a protective layer,
researchers have studied the decomposition behaviour of EVA nanocomposite using
nanofiller
...

Polyhydroxyalkanaotaes (PHA) represents a range of polymers obtained from
renewable resources by bacterial fermentation and a wide range of microbes have shown
the capability to generate this polymer

Reddy, Pratheep Kumar, & Singh, 2005)

...
Two approaches have been extensively described for this significant
challenge: (i) a covalent one consisting in a chemical functionalization, and (ii) a noncovalent
one based on interactions between active molecules and the CNTs’ carbon atoms
...
Additionally, the introduction of some
functionalities on the surface of CNTs allows noncovalent interactions or covalent links
(including grafting copolymeri- zation) to ensure good adhesion between the filler and the
surrounding polymer chains
...
Siengchin and Karger-Kocsis (2010) studied the mechanical and stress relaxation behavior of
SantopreneÒ thermoplastic elastomer/boehmite alumina nanocomposites
...
Though TPVs include different thermoplastics, the most widely used types are
polypropylene (PP)-based
...
The hardness and property profile of TPVs is
mostly controlled by the thermoplastic/rubber ratio, crosslinking degree of the rubber and
additional use of fillers and extender oils
...
According to Bhattacharya (2016), non-covalent functionalization of graphene has been
achieved via π-π stacking or van der Waals interactions
...
Graft and block copolymers
have been used as compatibilizers for polymer/CNT composites
...
This results in well dispersed CNTs in the
polymer matrix
