The invention relates to a method to produce polytetrahydrofuran (PTHF) copolymer from plant oil by copolymerizing epoxidized oil; preferably from natural sources like animal oils and more preferably from plants oils; with tetrahydrofuran (THF), in the presence of boron trifluoride-diethylether complex or tetrafluoroboric acid to yield the desired copolymer with specific properties. The properties of the produced PTHF copolymer depends on the (i) type of epoxidized oil used as co-monomer (ii) mole ratio between epoxidized oil and THF (iii) amount of catalyst (iv) reaction temperature (v) reaction time. The produced PTHF copolymers were then used as raw material for the production of polyurethane and polyurea.

A method of producing liquid polymeric polyols from epoxidized plant oils by ring-opening polymerization in an organic solvent in the presence of a catalyst to yield the desired polyols at room temperature. The properties of the polymeric polyols depend on the type of plant oil used as starting material. Typically, polymeric content of the purified plant oil based polyols ranges from 65% to 90%. The hydroxyl value and the acid value ranges from 30 to 90 mg KOH/g sample and 1 to 14 mg KOH/g sample respectively. The average molecular weight Mranges from 800 Da to 16000 Da. The liquid plant oil based polymeric polyols are reacted with excess diisocyanate to produce isocyanate terminated prepolymer. Subsequently, the prepared prepolymer is reacted with diol or diamine to polyurethane and polyurea respectively.

The present invention relates to a process for accelerated preparation of polyglycerol from crude glycerol using microwave irradiation as the heat element in the presence of soap as the catalyst. The process includes the steps of (a) heating the crude glycerol that contain soap to an elevated temperature for a certain reaction time by using a microwave technology, (b) acidifying the crude polyglycerol with mineral acid at a specific temperature and centrifuging acidified crude product obtained from step (b) at a specific temperature for a certain duration of time.

A process for preparing palm-based polyol monomer includes reacting unsaturated fatty acids or its corresponding triglycerides with polyhydric alcohol. In particular, one example uses oleic acid with about 70% purity as the starting material for preparing the polyol monomer. Moreover, another example uses refined, bleached, and deodorized (RBD) palm olein as an alternative to oleic acid as the starting material. The preparation of the polyol monomer involves the production of monoglyceride of unsaturated fatty acids, which was further epoxidized with peracid and finally ring opened with polyhydric alcohols. Such polyol monomer is used as a raw material for the production of various types of polyurethane products.
