본 발명은 구조 내에 P-OH그룹을 포함하고, X선 회절 분석 시 11.6±2도의 2θ 값에서 결정 피크를 가지며, 11.6±2도 미만의 2θ 값에서는 결정 피크가 관찰되지 않는 판상형 지르코늄포스페이트 에 관한 것이다. 본 발명에 의해 제조된 판상형 지르코늄포스페이트는 판상형 구조로 피막 내부에 나노크기로 균일하게 분산되어 표면 광택도 및 베리어 능력이 우수하고, 표면의 P-OH 기에 의해 내식성이 우수하며, 수용액뿐 아니라, 유기용매 등에도 분산 가능하다.
摘要:
The invention is related to a cost-effective method for producing water-soluble thermally-crosslinkable hydrophilic polymeric materials. Resultant materials can find particular use in preparing a packaging solution used for packaging and autoclaving medical devices, especially contact lenses. Those packaging solutions are especially suitable for forming a relatively-thick and soft hydrogel coatings on contact lenses or medical devices according to an in-package-crosslinking (IPC) processes. The resultant non-silicone hydrogel coatings can have a superior lubricity (a friction rating of 0) with minimized or no surface cracking.
摘要:
The undesirable odor of poly(phenylene ether) has discouraged its adoption for some end uses. Melt-blending poly(phenylene ether) with a small amount of a phosphate salt or its hydrate is found to substantially reduce the odor without affecting physical or thermal properties. The odor-reduction method is applicable to poly(phenylene ether) alone or in combination with other resins.
摘要:
A process is provided for converting discarded rubber, e.g., rubber crumb, into absorbent material. The process comprises extruding a mixture of discarded rubber and oxidizer(s) under progressively increasing temperature to reach a temperature above 250 °C. The extrudate may undergo a secondary oxidation. The partially devulcanized granular rubber formed is useful as absorbent material for hydrocarbons, e.g., in remediation of contaminated soil and oil spills.
