What are the properties of poly Chloroethene?
What are the properties of a polymer? Every polymer has very distinct characteristics, but most polymers have the following general attributes.
Polymers can be very resistant to chemicals.
Polymers can be both thermal and electrical insulators.
Generally, polymers are very light in weight with significant degrees of strength.
What is poly chloroethene made from? Poly(ethene) is a polymer made from a very large number of ethene molecules combined together. The reaction is called a polymerisation reaction : poly(ethene) is the polymer.
What type of polymer is poly propene? Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications.
It is produced via chain-growth polymerization from the monomer propylene.
Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar.

What are three general properties of polymers?
Physical properties of polymers include molecular weight, molar volume, density, degree of polymerization, crystallinity of material, and so on.
What are the two main types of polymers?
Polymers fall into two categories:
thermosetting plastic or thermoset.
thermoforming plastic or thermoplastic.
What are the properties and characteristics of smart polymers?
Smart polymers tend to have an all-or-nothing response, and are completely predictable, with the change being uniform throughout the material.
They might alter their conformation, adhesiveness or water retention properties, and can return to their initial state when the stimulus ends.
What can poly Chloroethene be used for?
Poly(chloroethene) is used in building and construction, for example in making window and door profiles and in making pipes (from guttering to sewers, and ducting for cables).
Chloroethene (vinyl chloride) is also used to produce co-polymers, for example with ethenyl ethanoate (vinyl acetate).
Is Poly Chloroethene saturated?
The original small molecule is called the monomer and the long molecule is called the polymer, which is the sort of molecule most plastic materials consist of. The polymer is now a saturated molecule but has the same C:H ratio as the original alkene.
What is poly Phenylethene used for?
The largest use for poly(phenylethene) is for packaging, particularly for foods such as poultry and eggs, for cold drinks and take-away meals.
Figure 1 Uses of poly(phenylethene).
It is also used in making appliances, including refrigerators, microwaves and blenders.
Why is poly propene chemically unreactive?
Poly(ethene) is chemically inert due to the strong C-C and C-H bonds and non-polar nature of the bonds and therefore is non-biodegradable.
The polymer chains consist of strong covalent bonds.
Increased chain length leads to increasing density, melting point and hardness.
What are the problems with polymers?
Most polymers, including poly(ethene) and poly(propene) are not biodegradable . This means that microorganisms cannot break them down, so they: cause a litter problem if disposed of carelessly. last for many years in landfill sites.
What type of polymer does not melt?
Thermosetting plastics do not melt when heated. They tend to char and burn when heated, but they are resistant to much higher temperatures than thermosoftening plastics.
What are 4 properties of polymers?
Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.
What are the 4 types of polymers?
Synthetic polymers are human-made polymers.
They can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers.
They are commonly found in a variety of consumer products.
What are the 3 main types of polymers?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
What is the revised classification of polymers?
The most common way of classifying polymers is to separate them into three groups – thermoplastics, thermosets, and elastomers.
The thermoplastics can be divided into two types – those that are crystalline and those that are amorphous.
What are the classification of polymers?
Classification of Polymers based on the Source of Availability.
There are three types of classification under this category, namely, Natural, Synthetic, and Semi-synthetic Polymers.
Is cotton a polymer?
Cotton fibers are the purest form of cellulose, nature’s most abundant polymer. Nearly 90% of the cotton fibers are cellulose.
What are smart polymers examples?
Examples of smart polymers are those that undergo rapid, reversible phase changes in response to small changes in environmental conditions.
