Synthesis And Characterization Of Bornylene And Bornadiene Polysulfone Resins

In this article, bornylene(Be), bornadiene (Bd) and SO₂ were used as the raw material to synthesis polysulfone resins, through free radical polymerization with different catalysts. The main copolymerization reactions including Be-SO₂, Be-SO₂-maleic anhydride (Ma), Be-SO₂- styrene(St), Bd-SO₂, Bd-SO₂- Ma, Bd-SO₂- St. The practicability and optimal experimental conditions of the copolymerization reaction of Be, Bd and SO₂ were investigated in our reasearch. Then the characterization work of the copolymers were carried out. The main results of this paper are as follows:(1) The Be, Bd monomers purity were enhenced from 92.1% and 98.3% to 95.3% and 98.5% respectively using different technologies and pathways. This step supplied high purity raw materials for the polymerization reactions.(2) The copolymers: Be-SO₂,Be-SO₂-Ma,Be-SO₂-St were prepared through free radical polymerization reactions. The molecular weight of the copolymers were 1069,1576,33054 respectively detected by GPC.(3) According to the pathways above, coplymers: Bd-SO₂, Bd-SO₂-Ma, Bd-SO₂-St were prepared, and the molecular weight of the copolymers were 1034,1896,37864 respectively detected by GPC.(4) The pathways, technologies and the optimal experimental conditions were put forward in this paper.(5) The preparation of new material polysulfone resin using pinene derivatives and SO₂ as raw material offers new directions and approaches for the resources application and atmospheric pollutant SO₂ in China .
