一次性玉米淀粉餐具的降解共聚物，在任一细微局部里，其空间较佳结构如下:当降解物质被降解之后，整体物质就被分割成一个个单独碎末几何体，而这些几何体分子量大幅度减低，很容易被自然界所消纳。在实际运作过程中重要解决：

The degradation copolymer of disposable corn starch tableware has the optimal spatial structure in any small area as follows: when the degradation material is degraded, the overall material is divided into individual fragmented geometric bodies, and the molecular weight of these geometric bodies is greatly reduced, making them easily absorbed by nature. In the actual operation process, it is important to address:

其一，降解物质和整体物质之间的作用力。

One is the interaction force between the degrading substance and the overall substance.

既然不是化学变化中的共价键力或离子键力，而牛顿万有引力又远远达不到产品强度的要求。因此，解决使其尽可能具有微观空间下的分子间作用力的问题。这是能降解共聚物生成难度的初个症结。

Since it is not covalent bonding force or ionic bonding force in chemical changes, and Newton's universal gravitation is far from meeting the requirements of product strength. Therefore, it is necessary to address the issue of maximizing the intermolecular forces in the microscopic space. This is the first crux of the difficulty in generating biodegradable copolymers.

其二，解决降解物质和整体物质之间的不融合性。

Secondly, address the non fusion between degradable substances and overall substances.

以淀粉和PE为例，前者为强极性分子，后者为非极性分子，两者不是相融、兼容，而是相憎相离，分子间作用力的形式单一，作用力较小。解决的办法，是在两者之间加入交联剂、偶联剂、表面活性剂等物质。这是能降解共聚物生成难度的第2个症结。

Taking starch and PE as examples, the former is a strongly polar molecule, while the latter is a non-polar molecule. The two are not compatible or compatible, but rather mutually exclusive. The form of intermolecular forces is single, and the forces are relatively small. The solution is to add crosslinking agents, coupling agents, surfactants, and other substances between the two. This is the second crux of the difficulty in generating biodegradable copolymers.

当然，在进入到一次性玉米淀粉餐具实际批量生产时，还要辅之以特定的引发剂、自氧化剂等等，使合成树脂体系结构在光、热、氧以及微生物的化学作用下，发生自主基的连锁反应而使其分子量大幅度减低从而达到深部降解。

Of course, when entering the actual mass production of disposable corn starch tableware, specific initiators, self oxidizers, etc. need to be supplemented to make the synthetic resin system structure undergo a chain reaction of self radicals under the chemical action of light, heat, oxygen, and microorganisms, resulting in a significant reduction in its molecular weight and deep degradation.

勿容置疑，在新的降解树脂共混合体中，塑料等传统树脂不是单独连续的结构。新式共混整体应该是处处近似均匀，处处近似连续的相异多粒子体。另外，为了接近优良空间，每种组份的颗粒还应该周全地小。

Undoubtedly, in the new degradation resin blend, traditional resins such as plastic are not individually continuous structures. The new type of blending should be a heterogeneous multi particle body that is approximately uniform and continuous everywhere. In addition, in order to approach the optimal space, the particles of each component should also be carefully small.
