What types of bond butene contain?
Butene is an unsaturated hydrocarbon molecule and therefore contains a Carbon-Carbon double bond.The molecule can be used as a monomer and through additional polymerisation multiple molecules can be combined to result in polybutene.
What are the similarities between addition polymerization and condensation polymerization?
Polymerization describes the formation of of large molecules (polymers) with repeating structure from smaller molecules (monomers) . The word polymer comes from Greek words meaning many (poly-) and parts (-mer). Many of the resulting molecules are plastics, so polymer is occasionally used in place of the word plastic, though this is not an accurate usage. Polymerization is an all-encompassing term that describes formation of polymers by any method.There are two main types of polymerization; addition polymerization and condensation polymerization. Addition polymerization creates larger molecules by opening up double bonds on the smaller molecules (monomers). These opened-up bonds react with parts of other monomers (single part) to form dimers (double part). This reaction can repeat to add another molecule to for a trimer (three part). This continues until you obtain the right size molecule and you stop the reaction. Addition polymerixation can occur using a single type of monomer. There are no by products of the reaction except the longer chain molecules (polymers).In condensation polymerization, two monomers of different types are used. They have different types of reactive (or functional) groups on them. A reaction between monomer A and monomer B results in a dimer, plus another small molecule (often water) that is not part of the polymer. To create long polymers the monomers must have reactive groups on both ends or a chain cannot be formed.Polymerization is an all-encompassing term for creating polymers by any method. Condensation Polymerization is a term denoting a specific type of reaction for creating polymers.
What are the uses of unsaturated hydrocarbons?
Used as a POLYMERS.
Are monomers made up of many polymer units?
No. Amino acid monomers are used to make protein polymers. Nucleotide monomers are used to make DNA polymers.
What reagent is used to test for unsaturated hydrocarbons?
This reagent is bromine in solution.
What happens in polymerisation?
According to Sci-Tech Encyclopedia, as quoted on Answers.com, The linking of small molecules (monomers) to make larger molecules. There are two primary ways this linking occurs, condensation method, and the addition method. Both require a catalyst, such as an acid, or a heat source, depending on which method is used. For a more complete discussion of this subject, see the excellent article on Answers.com For a children's version of the explanation of polymerisation, see this excellent "Making Science Fun" article: http://www.stevespanglerscience.com/experiment/00000039
What is the name of the chemical reaction which combines monomers to make polymers?
Simply - polymerization. However, this is usually addition polymerization but not always. Nylon is formed by condensation polymerization and the polymers used to make waterbased latex paints is usually called emulsion polymerization.
What is the role of polymerization in making replacement hip joints?
polymerisation is used to combine the different monomers to make a polymer for hip replacement which wear well with the movement of the joint.

What technology is used in the manufacturing of polythene?
Polymerisation
What is the term for the building block of polymers?
Monomers

What is poly-propylene?
Polypropylene is a versatile polymer. It is used both as a plastic and as a fiber. Polypropylene is also known as polypropene. Polypropene is a polymer made up of monomers of propene (an alkene). In the presence of high pressure, high heat and the use of a catalyst, these monomers undergo an addition reaction whereby the monomers are joined together into a long chain known as a polymer. Nomenclature can be derived from "poly" meaning 'many' and "propene" the alkene with three carbon particles.

Used as a POLYMERS.
What are short molecules used to make polymers?
monomers
What do lipids and proteins have in common?
Proteins and lipids are both biological macromolecules, which means they are made up of monomers (indiviudal units) to form polymers (many units). They are both formed by dehydration synthesis and broken apart by hydrolysis. In addition, their monomers can both be used as alternate forms to carbohydrates in the metabiolic pathway of cellular respiration.
