摘要: 本文采用含氯硅烷或硅氧烷与含羟基的单乙烯基醚的取代反应合成了8种含硅乙烯基醚单体,并研究了它们的物理化学性质和光聚合反应过程. 该合成反应过程简单、产率高,是合成含硅乙烯基醚单体的有效方法. 性质研究表明6种单体黏度合适,6种单体热稳定性好;光聚合反应研究表明,随着引发剂浓度(< 2.4wt %时)增加,单体聚合反应速率随之增大. 双官能度的单体在聚合速率和诱导期上表现整体优于单官能度单体. 含硅乙烯基醚单体的固化速率非常快,可以通过增加产酸剂浓度或光强来提高双键转化率.

Abstract: Eight different silicon-containing vinyl ether monomers were synthesized by the substitution reaction of hydroxyl-containing monovinyl ether with various chlorosilanes and chlorosiloxanes. It is a effective method to obtain silicon-containing vinyl ethers because of simple process and high yield. The physical and chemical properties and photocuring kinetics of these photosensitive compounds initiated by PAG201 were investigated by Integrated Thermal Gravimetric Analyzer and Real Time Infrared. The study on properties indicated that there are six monomers with the appropriate viscosity and six monomers had good thermal stability. The photopolymerization kinetic results showed that an increase of the initiator content (< 2.4wt %) strongly accelerated the photopolymerization of the photocuring monomers and the maximum of the polymerization rate was achieved earlier. The performance of photopolymerization of the difunctional monomers was superior to monofunctional monomers. Silicon-containing vinyl ethers had a very fast curing rate and could enhance the DC% by increasing the PAG content or the light intensity.
