BackgroundSynthetic polymers are ubiquitous, finding wide-ranging applications far beyond use in plastics and packaging. For example, vinyl and acryl polymers are extensively utilised in the preparation of high-performance coatings, adhesive, sealants and elastomers, and thus present in products we are in contact with on a daily basis. However, the vast majority of vinyl and acryl polymers are derived from non-renewable fossil resources and therefore have a detrimental carbon impact and long-term supply concerns. Biomass derived vinyl and acryl polymers are of significant commercial interest on the basis of improved carbon impact. The challenge is preparing vinyl and acryl polymers from biomass of appropriate performance, whilst also ensuring the chosen pathways of production are both sustainable and scalable. Prior research into bio-based vinyl and acryl polymers typically proceeds via non-catalytic wasteful reactions and in many instances fails to exploit the high chemical functionality of bio-based chemicals. Project Objectives1. Demonstrate vinyl and acryl furans, derivable from biomass, can be used as appropriate substitutes for current petrochemical monomers such as styrene and acrylates in chain-growth polymerisation 2. Develop new synthetic pathways, applying catalysis for the optimised synthesis of target bio-based monomers3. Progress the use of bio-based polymers in coatings, adhesives, sealants and elastomers, working alongside the project's industry partner Synthomer4. Scope commercialisation pathways for the most promising candidates you have preparedExperimental approachThe project will address the above objective via synthesis of a range of different bio-derivable vinyl and acryl furans monomers at lab-scale, allowing for preliminary assessment of their use in emulsion and solvent-phase chain-growth polymerisation. Where appropriate, the project will seek to develop catalytic approaches for the preparation of some monomers. The project will characterise lab-scale polymers and select those with the most promising properties for use in coatings, adhesives, sealants, and/or elastomers. The project will select further target monomers and polymers based upon ease of synthesis and preliminary property data you have gathered from your earlier results. Scale-up of the synthesis (>500 g) for the leading monomers and polymers will take place in the latter half of the project, and data gathered on their performance in relevant applications as tested by Synthomer.Novelty and impactThis project will provide fundamental insights into the suitability of using furan-containing monomers in synthesis of novel vinyl and acryl chain-growth polymers. The project will address a gap in the systematic understanding of the role of different functional groups present on furan monomers has on ultimate polymer performance. This study will also address a gap in the effective application of catalytic methods for the synthesis of vinyl and acryl furan polymers. Ultimately, we seek to commercialise these new sustainable materials, potentially bringing new products to market and seeding a new generation of high bio-content polymers.

合成聚合物无处不在，其应用范围远远超出塑料和包装。例如，乙烯基和丙烯酸聚合物广泛用于制备高性能涂料、粘合剂、密封剂和弹性体，因此存在于我们每天接触的产品中。然而，绝大多数乙烯基和丙烯基聚合物来自不可再生的化石资源，因此具有有害的碳影响和长期供应问题。基于改善的碳影响，生物质衍生的乙烯基和丙烯基聚合物具有显著的商业利益。挑战在于从适当性能的生物质中制备乙烯基和丙烯基聚合物，同时确保所选的生产途径既可持续又可扩展。对生物基乙烯基和丙烯基聚合物的先前研究通常通过非催化浪费反应进行，并且在许多情况下未能利用生物基化学品的高化学官能度。项目目标1.证明乙烯基和丙烯基呋喃，衍生自生物质，可用作适当的替代品，目前的石化单体，如苯乙烯和丙烯酸酯在链增长聚合2。开发新的合成途径，应用催化剂优化目标生物基单体的合成3。与该项目的行业合作伙伴Synthomer 4合作，推进生物基聚合物在涂料、粘合剂、密封剂和弹性体中的应用。范围商业化途径为最有前途的候选人你已经确定实验方法该项目将通过在实验室规模合成一系列不同的生物衍生的乙烯基和丙烯基呋喃单体，以解决上述目标，允许其在乳液和溶剂相链增长聚合的使用进行初步评估。在适当情况下，该项目将寻求为某些单体的制备开发催化方法。该项目将筛选实验室规模的聚合物，并选择那些具有最有前途的性能的聚合物用于涂料，粘合剂，密封剂和/或弹性体。该项目将根据您从早期结果中收集的合成容易程度和初步性能数据选择进一步的目标单体和聚合物。主要单体和聚合物的合成规模（>500 g）将在该项目的后半部分进行，并收集Synthomer测试的相关应用中的性能数据。新奇和影响该项目将提供关于在合成新型乙烯基和丙烯基链增长聚合物中使用含呋喃单体的适用性的基本见解。该项目将解决在呋喃单体上存在的不同官能团对最终聚合物性能的作用的系统理解方面的差距。本研究还将解决乙烯基和丙烯酰基呋喃聚合物的合成的催化方法的有效应用的差距。最终，我们寻求将这些新的可持续材料商业化，有可能将新产品推向市场，并为新一代高生物含量聚合物提供种子。
