[Chemical Structure Diagram]

2. Basic principles of polyurethane synthesis

2.1 Synthesis of polyurethane

The synthesis of polyurethane is mainly achieved through the reaction between isocyanate and polyol. The reaction is usually divided into two stages:

Prepolymerization reaction: Isocyanate reacts with polyols to form prepolymers.
Chain Extended Reaction: The prepolymer reacts with a chain extender (such as diol or diamine) to form a high molecular weight polyurethane.

2.2 The role of catalysts in polyurethane synthesis

The catalyst plays a role in accelerating the reaction rate and controlling the reaction process in polyurethane synthesis. Commonly used catalysts include organotin compounds, amine compounds, etc. Due to its temperature sensitivity, the thermosensitive catalyst SA-102 can significantly increase the reaction rate at a specific temperature, thereby achieving precise control of the reaction process.

III. Adaptation of SA-102 to polyurethane reaction temperature

3.1 Temperature sensitivity of SA-102

The catalytic activity of SA-102 varies significantly with temperature. Below 50°C, its catalytic activity is lower and its reaction rate is slower; while in the range of 50-120°C, its catalytic activity is significantly enhanced with the increase of temperature. This temperature sensitivity gives SA-102 the following advantages in polyurethane synthesis:

Controlable reaction rate: By adjusting the reaction temperature, the reaction rate can be accurately controlled to avoid excessive or slow reaction.
Reduce side reactions: At low temperatures, SA-102 has low catalytic activity, which reduces the occurrence of side reactions and improves the quality of the product.
Energy-saving and environmentally friendly: The reaction rate is slow at low temperatures, which reduces energy consumption and meets environmental protection requirements.

70	60	1.0	Excellent
90	30	2.0	Excellent
110	15	4.0	Good
120	10	5.0	General

It can be seen from the table above that as the temperature increases, the catalytic activity of SA-102 is significantly enhanced and the reaction rate is accelerated. However, when the temperature exceeds 110°C, the reaction rate is too fast, which may lead to a degradation of product performance. Therefore, in practical applications, the appropriate reaction temperature should be selected according to the specific needs.
