SBS接枝丙烯酸酯类能改善胶液对PVC人造革的黏合性.若在此体系中引入高氯含量的氯化聚氯乙烯CPVC与SBS并用,可进一步提高性能.以质量比为10:3.0的甲苯、丁酮混合液作溶剂,其用量为骨架聚合物(SBS CPVC)用量的4.0倍,引发剂2.0%,单体70%,温度控制在90±1 ℃.在此工艺条件下研究了CPVC、SBS与MMA的三元接枝共聚反应,并用红外光谱对接枝产物进行了表征.实验表明,CPVC和SBS必须采用分步法溶解,即待CPVC溶解完全后,再加SBS溶解.CPVC在体系中的含量不能过高,否则,胶层在拉伸时易脱离基材,放置过程中也易分层.CPVC用量为骨架聚合物总用量的20%～30%时,所制胶黏剂的贮存稳定性及耐水性能较好,对PVC材料的黏合强度亦较高.

Adhesive and Rheological Properties of Lightly Crosslinked Model Acrylic Networks

The viscoelastic and adhesive properties of a series of model, lightly crosslinked acrylic polymer networks have been investigated. The model networks were statistical copolymers of 2-ethyl-hexyl acrylate and acrylic acid or terpolymers of 2-ethyl-hexyl acrylate, acrylic acid, and stearyl acrylate synthesized in solution. All were lightly crosslinked after the polymerization was completed to obtain typical properties of pressure-sensitive adhesives. The bulk rheological properties of the networks were characterized by dynamical mechanical spectroscopy and in uniaxial extension. Their adhesive properties were tested with an instrumented probe tester fitted with a cylindrical steel probe. The presence of acrylic acid in the copolymer caused an increase in both elastic modulus and resistance to interfacial crack propagation characterized by the critical energy-release rate G_c and the incorporation of stearyl acrylate caused a decrease in both modulus and G_c. In both cases, however, the modification of G_c controlled the overall behavior. The analysis of the nonlinear elastic properties of the adhesives with the Mooney-Rivlin model provided new insights on the role played by the ratio between entanglements and crosslink points in controlling the formation and extension of the bridging fibrils observed upon debonding.
