This Small Business Innovation Research Phase I project will investigate the development of performance bio-based latex from alkyl itaconates for application in wood coatings. Identified by DOE in 2004 as a top 12 renewable chemical, itaconic acid and its derivatives have potential use in polymers for a variety of products from builders in detergents to binders in paints and coatings. Itaconix has successfully produced stable alkylitaconate bio-based latexes using its patent-pending green emulsion polymerization process. The current performance of these latexes is not sufficient to overcome marketplace inertia favoring the well-established petroleum-based latexes.This research will combine a new model-based approach and Itaconix?s existing polymer expertise to (a) identify the key synthesis parameters necessary to enhance cohesion and adhesion and (b) minimize hydroplastization effects. The key to controlling these parameters is to optimize the morphology of the structured latex particles. The goal is to create core-shell type geometries where a hard core acts like a hydrophobic reinforcement domain and the soft shell provides film-forming properties. The Broader Impact/commercial potential of this project will be market acceptance and use for optimized alkylitaconate latexes that offer superior price/performance over current latexes in certain wood coatings. With this commercial breakthrough, we will open the potential for developing favorable bio-refining economics and leveraging efficient latex production technologies that will enable broader use of bio-latexes. While bio-based chemicals rapidly capture the interest of customers and generate application testing, they rarely command more than a slight price premium over petroleum-based chemicals. To succeed commercially and reduce our dependence on petroleum, bio-based latexes need to offer compelling price/performance advantages.Current paint and coatings manufacturers face wide price variations from petroleum-based monomers and latexes, often requiring costly product reformulations and adjustments. A long-term expected advantage from bio-based materials is more stable sourcing and formulations. Our research is expected to generate initial market acceptance and use for optimized alkylitaconate latexes that offer superior price/performance over current latexes in certain wood coatings. With this commercial breakthrough, we will open the potential for developing favorable bio-refining economics and leveraging efficient latex production technologies that will enable broader use of bio-latexes.

这个小企业创新研究第一阶段项目将研究从衣康酸烷基酯中开发高性能生物基胶乳，用于木器涂料。2004年被美国能源部确定为12大可再生化学品，衣康酸及其衍生物在聚合物中具有潜在的用途，可用于各种产品，从洗涤剂中的助洗剂到油漆和涂料中的粘合剂。Itaconix已成功地生产了稳定的烷基衣康酸生物基胶乳使用其专利申请中的绿色乳液聚合工艺。 目前的表现，这些乳胶是不足以克服市场惯性，有利于完善的石油为基础的latexes.This研究将联合收割机一个新的模型为基础的方法和Itaconix？公司现有的聚合物专业知识，以（a）确定必要的关键合成参数，以提高凝聚力和附着力和（B）尽量减少水塑化效应。 控制这些参数的关键是优化结构化乳胶粒子的形态。 目标是创建核-壳型几何结构，其中硬核充当疏水增强域，软壳提供成膜性质。该项目的更广泛影响/商业潜力将是市场接受和使用优化的衣康酸烷基酯胶乳，在某些木材涂料中提供比当前胶乳更上级的价格/性能。 通过这一商业突破，我们将开发有利的生物精炼经济学和利用高效的乳胶生产技术，使生物乳胶得到更广泛的使用。虽然生物基化学品迅速吸引了客户的兴趣并进行了应用测试，但它们的价格很少超过石油基化学品。 为了在商业上取得成功并减少我们对石油的依赖，生物基乳胶需要提供令人信服的性价比优势。目前的油漆和涂料制造商面临着石油基单体和乳胶的广泛价格差异，通常需要昂贵的产品重新配方和调整。 生物基材料的长期预期优势是更稳定的来源和配方。 我们的研究预计将产生初步的市场接受和使用优化的烷基衣康酸酯胶乳，提供上级价格/性能比目前的胶乳在某些木材涂料。 通过这一商业突破，我们将开发有利的生物精炼经济学和利用高效的乳胶生产技术，使生物乳胶得到更广泛的使用。
