polymers Flashcards
starch is a homopolymer of
glucose
cellulose is a homopolymer of
glucose
name the monomers that make up glycogen ,polyvinylchloride, teflon and nylon-6 resp
glycogen-glucose
polyvinylchloride-vinyl chloride
teflon-tetrafluoroethylene
nylon-6:caprolactum
give 4 examples of semisynthetic polymers
cellulose xanthate.
cellulose acetate
cellulose nitrate
rayon
what category on the basis of shape of polymers does nylon come under
linear
compare the densities of linear and branched polymers with reasoning
linear polymers have higher density as they closed packed ,thus occupying less volume and thus ,less density
amylopectin comes under what category of polymers on the basis of shape
branched
resins come under what type of polymers on the basis of shape
cross linked
dacron made of
terephalic acid and ethylene glyvol
nylon 6 ,6 made of
nylon 6
caprolactum
novolac on heating forms what
bakelite
how many sp2 n does melamine have
6
what is added to rubber for vulcanisation
natural ubber is a cis polymer or trans isomer
neoprene is polymer
butyl rubber is a copolymer of
buna s is a copolymer of
gutta percha is a polymer of
—– is resistant to action of oils,ozone and gasoline
structure of melamine
structure of bakelite
is bakelite thermoplastic or thermosetting
thermosetting
——is crease resistant and absorbs less moisture

what type of rubber is used to make waterproof coats
natural rubber ….i e cis isoprene
nylon 2 nylon 6 is a copolymer of
glycine and caproic acid
unbreakable crockery is made from
