General description

Pentaerythritol is acrystalline , odour less white solid. The presence of neopentane core and four terminalhydroxyl groups makes it a versatile substrate for the synthesispolyfunctionalized compounds.

Application

Pentaerythritol can be used as a starting material to prepare four armed polyurethane prepolymers, which are applicable in the synthesis of UV cured polyurethane dispersions.

It can be used as an additive in the preparation of flame retardant polymers.

It can also be used as a precursor to synthesize polyethylene glycol/4,4′-diphenylmethane diisocyanate/pentaerythritol copolymer which is applicable as heat storage material.

Bio-based unsaturated poly(butylene adipate-co-butylene itaconate) (PBABI) aliphatic copolyesters were synthesized with pentaerythritol (PE) as a modifier, observing the melting point, crystallization, and glass transition temperatures were decreased from 59.5 to 19.5 °C and 28.2 to -9.1 °C as an increase

In this study, we synthesized and characterized a series of macromers based on poly( N-isopropylacrylamide) that undergo thermally induced physical gelation and, following chemical modification, can be chemically cross-linked. Macromers with number average molecular weights typically ranging from 2000-3500 Da

Delivery of siRNA into cells remains a critical challenge. Our lab has shown a novel polyamidoamine (PAMAM) dendrimer with modified pentaerythritol derivative core (PD dendrimer) to exhibit high plasmid DNA transfection efficiency and low cytotoxicity. Here, we evaluate PD dendrimer

Polyamidoamine (PAMAM) dendrimers represent one of the most efficient polymeric gene carriers. This study describes a new family of PAMAM dendrimers that can be synthesized using a Pentaerythritol derivative (PD) as a core that possesses 12 branches. This new approach
