Chapter IINTRODUCTION:Now a days we are
facing a potential condition in climate such as rain, flood, typhoon and etc.
If we can hear news that there is a rain coming, we often think that it is a
new problem. It maybe can cause flood of we are worried because we have holes
in our roof.In order to solve this
problem, The researchers will investigate about the wasted polystyrene as a
substitute for sealant. Researcher came up with this problem because as they
observe in some houses, many have holes in the roof. The researcher are sure
that many people will benefit this study whether they are rich or poor, the
main reason why we choose this study because it is affordable. Instead of
buying a sealant, you can just recycle some of the wasted polystyrene and make
it a sealant.IMPORTANCE
OF THE STUDYWeather changes
constantly now a days, and our houses are one of the provides for our safety
against any harm being brought by this phenomenon, but due to this weather
condition our houses are also the victim of the events that is caused by this
condition, one of the most affected on our houses was the roof because it
receives most of weather’s impact such as rains, heat from the sunlight,
humidity and etc. that either cause the roof to be more fragile and rusted or
create rainwater to drip down more the houses.The researchers
ascertained that using Styrofoam  as an
alternative roof sealant will provide the same reliable effects as any branded
roof sealant; with much cheaper and can create unlimited supply and the user
also because Styrofoam were frequently used yearly this project helps to reduce
the number of Styrofoam being thrown elsewhere, which cause certain calamities
that may ruin most of the place’s properties. STATEMENT
OF THE PROBLEM:-Can Styrofoam become /
transformed into sealant?-Can Styrofoam,
combined with gasoline, to form a reliable sealant?-Is the polystyrene
effective as a roof sealant? RESEARCH
HYPOTHESIS:In this study, we want
to prove that a wasted polystyrene can be also a good substitute to sealant and
this project is much cheaper that we can afford. 

SCOPE
AND LIMITATION:
This study is only limited on using a Styrofoam because Styrofoam is the one
thing that can be melted by the petroleum fuel or gas. The Researchers will not
use only any kind of polystyrene besides Styrofoam and gasoline as the dissolver
agent. The study is only limited on the projects that creates the same around
as the solvent we use in creating this product.Styrofoam is a initials name for polystyrene
thermal insulation material, Created by Daw Chemical Company. Styrofoam can be
also used for building materials including insulated sheathing, floral and
craft products. Styrofoam insulation has been used in many distiguised building
and facilities in the world. Styrofoam can be used underneath roads and other
structures to prevent soil disturbances due to seasonal freeze. When the
Styrofoam heated above its glass transition temperature, it turns into liquid
form and become solid again when it cools off and it dissolve in some organic
solvents. In the 1940’s Daw invented a process for extruding polystyrene to
achieve closed cell foam that resist moisture. In recognition of its insulating
properties, buoyancy and “unsinkabilty” it was originally adopted in 1942 by
the Coast Guard for use in six-man life raft, the Daw Chemical Company works to
educate the public that Styrofoam is a registered trademark rather than a
genetic term for polystyrene foam. Dow also produces Styrofoam as structural
insulated panels for use by florists in white and green. Polystyrene is a
synthetic aromatic polymer made from the monomer styrene. Polystyrene is a
synthetic aromatic polymer made from the monomer styrene. Polystyrene, it can
be a solid formed or liquid form , the one most widely used plastic is
Polystyrene.
