Ko te raupapa SORT resin terpene he polymer linear thermoplastic i hangaia mai i te hinu turpentine kua tohua hei papanga turanga.I muri i te para, ka tohua nga monomers me te whakakotahi, ka mahia te polymerization me Friedel-Crafts hei whakakorikori, ka mahia te hydrolysis, te horoi, te filtration me te whakamarumaru.He pai mo te whakarite i te EVA, SIS, SBS wera rewa whakapiri me etahi atu taapiri e hiahia ana ki te pokey tuatahi me te kaha o te whakakotahitanga.
